Question 1.
A small candle 2.5 cm in size is placed 27 cm in front of a concave mirror of radius of curvature 36 cm. At what distance from the mirror should a screen be placed in order to receive a sharp image ? Describe the nature and size of the image. If the candle is moved closer to the mirror, how would the screen have to be moved ?
Answer:
Here, h = 2.5 cm, u = – 27 cm, R = – 36 cm.
NCERT Solutions for Class 12 physics Chapter 9
Nature of image : Real, inverted and magnified. When the position of the object (i.e. candle) is moved closer to the concave mirror, the distance of the image moves away from the screen till the distance of the candle from the concave mirror is less than 18 cm. Hence, the screen has to be moved away from the concave mirror. When the distance of the candle is less than 18 cm from the concave mirror, a virtual and magnified image of the candle is formed behind the mirror. This image is not obtained on the screen.

Question 2.
A 4.5 cm needle is placed 12 cm away from a convex mirror of focal length 15 cm. Give the location of the image and magnification. Describe what happens as the needle is moved farther from the mirror.
Answer:
Here, h1 = 4.5 cm, μ = – 12 cm, f= 15 cm
vedantu class 12 physics Chapter 9.1
Thus, the image is virtual, erect and diminished. As we move the needle away from the mirror, the image goes on decreasing in size and moves towards the principal focus on the other side.

Question 3.
A tank is filled with water to a height of 12.5 cm. The apparent depth of the needle lying at the bottom of the tank is measured by a microscope to be 9.4 cm. What is the refractive index of water ? If water is replaced by a liquid of refractive index 1.63 up to the same height, by what distance would the microscope have to be moved to focus on the needle again ? (C.B.S.E. 2009 )

Question 5.
A small bulb is placed at the bottom of a tank containing water to a depth of 80 cm. What is the area of the surface of water through which light from the bulb can emerge out ? Refractive index of water is 1.33 (consider the bulb to be a point source).
Answer:
vedantu class 12 physics Chapter 9.5
The light rays from the bulb B, which fall on the surface of water at an angle equal to critical angle (θC), grazes on the surface of water and the rays of light which fall on the surface of water at an angle greater than θC are totally internally reflected back into the water. The rays of light images emerges out of water through a circular patch of radius r.

Question 7.
Double-convex lenses are to be manufactured from a glass of refractive index 1.55, with both faces of the same radius of curvature. What is the radius of curvature required if the focal length is to be 20 cm ?
Answer:
Here, n = 1.55, R1 = R and R2 = – R, f= 20 cm Using lens maker formula, we get
NCERT Solutions for Class 12 physics Chapter 9.9
Question 8.
A beam of light converges to a point P. A lens is placed in the path of the convergent beam 12 cm from P. At what point does the beam converge if the lens is (a) a convex lens of focal length 20 cm, (b) a concave lens of focal length 16 cm ?
Answer:
(a) When a convex lens is placed in the path of light converging at P, the beam converges at Pt. Thus, point P acts as virtual object for the convex lens.
Now, u = 12 cm, f= 20 cm.

Question 9.
An object of size 3.0 cm is placed 14 cm in front of a concave lens of focal length 21 cm. Describe the image produced by the lens. What happens if the object is moved farther from the lens ?
Answer:
NCERT Solutions for Class 12 physics Chapter 9.12
Thus, the image is virtual, erect, diminished and is formed on the same side of the lens at a distance of 8-4 cm from the lens. If the object is moved away from the lens, the image moves towards the principal focus and goes on decreasing in size.

Question 10.
What is the focal length of a convex lens of focal length 30 cm in contact with a concave lens of focal 
length 20 cm ? Is the system a converging or a diverging lens ? Ignore thickness of the lenses.
Answer:
Here, f1 = 30 cm and f2 = -20 cm
For the combination of two thin lenses, the focal length of the combination is given by
NCERT Solutions for Class 12 physics Chapter 9.13
Since the focal length of the system of lens is negative, therefore, the combination behaves as a diverging lens.

Question 11.
A compound microscope consists of an objective lens of focal length 2-0 cm and an eye-piece of focal length 6.25 cm separated by a distance of 15 cm. How far from the objective should an object be placed in order to obtain the final image at
(a) the least distance of distinct   vision (25 cm), (b) infinity ? What is the magnifying power of the microscope in each case ? (C.B.S.E. 2008)
Answer:
Here, fn =2.0 cm, f = 6.25 cm,
Distance between object lens and eye piece = 15 cm (a) For the formation of image at the least distance of distinct vision,

vedantu class 12 physics Chapter 9.26
Therefore all incident rays in the range 0 to 90°suffer total internal refletion.

Question 18.

Answer the following questions :
(a) You have learned that plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstances ? Explain.
(b) A virtual image, we always say, cannot be caught on a screen. Yet when we ‘see’ a virtual image, we are obviously bringing it on to the ‘screen’ (i.e., the retina) of our eye. Is there a contradiction ?
(c) A diver under water, looks obliquely at a fisherman standing on the bank of a lake, would the fisherman look taller or shorter to the diver than what he actually is ?
(d) Does the apparent depth of a tank of water change if viewed obliquely ? If so, does the apparent depth increase or decreases
(e) The refractive index of diamond is much greater than that of ordinary glass. Is this fact of some use to a diamond cutter ?
Answer:
(a) Yes. They can produce real images if the object is a virtual object as shown in figure.
NCERT Solutions for Class 12 physics Chapter 9.27
(b) here is no contradiction in this case. The virtual image of the object acts as an object for the convex lens of our eye and the lens of our eye make a real image of this object on the ratina.
(c) Let AB be the fisherman standing on the bank of the lake. The rays of light from the head of the fisherman bends towards the normal on refraction at the interface separating water and air. The refracted rays appear to come from point B’ instead of point B for the fish. Thus, for a diver the height of the fisherman is AB’ which is greater than his actual height AB.
NCERT Solutions for Class 12 physics Chapter 9.28
(d) The apparent depth of a pond of water decreases when viewed obliquely. This is due to the refraction of light from the surface of water.

Question 23.
You are given prism made of crown glass and flint glass with a wide variety of angles. Suggest a combination of prisms which will 
(a) deviate a pencil of white light without much dispersion (b) disperse (and displace) a pencil of white light without much deviation.
Answer:
(a) 
Angular dispersion produced by two prisms i.e. crown glass and flint glass should be zero in this case
NCERT Solutions for Class 12 physics Chapter 9.36
NCERT Solutions for Class 12 physics Chapter 9.37
In the combination of prisms, flint glass prism of greater angle may be tried but in any case still this angle will be smaller than the angle of the crown glass prism in opposite order as shown in figure.

Question 24.
For a normal eye, the far point is at infinity and the near point of distinct vision is about 2.5 cm in front of the eye. The cornea of the eye provides a converging power of about 40 dioptres, and the least converging power of the eye lens behind the cornea is about 20 dioptres. From this rough data estimate the range of accommodation {i.e., the range of converging power of the eye-lens) of a normal eye.
Answer:
When the object is placed at infinity, the eye makes use of the least converging power, Therefore, total converging power of cornea and the eye lens = 40 + 20 = 60 dioptre.
vedantu class 12 physics Chapter 9.38

Question 25.

Does short-sightedness (myopia) or long-sightedness (hypermetropia) imply necessarily that the eye has partially lost its ability of accommodation ? If not, what might cause these defects of vision ?
Answer:
No. Myopia may arise due to the elongation of the eye ball and hypermetropia may arise due to the decrease in the size of the eye ball even when the eye has the normal ability of accommodation. There is another defect in the eye called presbyopia similar to hypermetropia. However, the causes of presbyopia and hypermetropia are different. Presbyopia arises in elderly persons and is corrected by using a bi-focal lens.

Question 26.
A myopic person has been using spectacles of power – 1.0 dioptres for distant vision. During old age he also needs to use separate reading glass of power 
+2 dioptres. Explain what may have happened.
Answer:
For -1.0 dioptre, the far point for eyes is 1 m 
i.e. 100 cm. The near point is 25 cm. The objects lying at infinity are brought at 100 cm from his eyes using the concave lens and the objects lying in between 25 cm and 100 cm are brought to focus using the ability of accommodation of the eye lens. In the old age, this ability of accommodation is reduced and the near point reaches 50 cm from his eyes.
NCERT Solutions for Class 12 physics Chapter 9.39


Question 27.

A person looking at a mesh of crossed wires is able to see the vertical wires more distinctly than the horizontal wires. What is this defect due to ? How is such a defect of vision corrected ?
Answer:
This is due to the defect of lenses called astigmatism. The defect arises because of the fact that curvature of the eye-lens and the cornea is not same in different planes. This defect is removed by using cylindrical lens with vertical axis.

Question 28.
A man with normal near point (25 cm) reads a book with small print using a magnifing glass : a thin convex lens of focal length 5 cm.
(a) What is the closest and the farthest distance at which he can read the book when viewing through the magnifying glass ?
(b) What is the maximum and minimum angular magnification (magnifying power) possible using the above simple microscope ?
Answer:
(a) To see the object at a closest distance, the image of object should be formed at the least distance of distinct vision.

NCERT Solutions for Class 12 physics Chapter 9.41
Question 29.
A card sheet divided into squares each of size 1 mmis being viewed at a distance of 9 cm through a magnifying glass (a converging lens of focal length 10 cm) held close to eye.
(a) What is the magnification (image size/object size) produced by the lens ? How much is the area of each square in the virtual object ?
(b) What is the angular magnification (magnifying powers) of the lens ?
(c) Is the magnification in
(1) equal to magnifying power in
(2) ? Explain.
Answer:
vedantu class 12 physics Chapter 9.42
(c) Clearly magnification and power magnification are not equal to each other unless the image is located near the least distance of distinct vision, e. v = D.

Question 30.
(a) At what distance should the lens be held from the figure in the above exercise in order to view the squares distinctly with maximum possible magnifying power ?
(b) What is the magnification (image size/object size) in this case ?
(c) Is the magnification equal to magnifying power in this case ? Explain.
Answer:
(a) The magnifying power is maximum if the image is formed at the least distance of distinct point from the eye, i.e., if υ = -25 cm ; Also, f = 10 cm
NCERT Solutions for Class 12 physics Chapter 9.43
=> the linear magnification and magnifying power is equal in this case.

Question 31.
What should be the distance between the object in the previous exercise and the magnifying glass if the virtual image of each square in the figure is to have an area 6.25 mm2 ? Would you be able to see the squares distinctly with your eyes very close to the magnifier ?
Answer:
NCERT Solutions for Class 12 physics Chapter 9.44

Question 32.

Answer the following questions :
(а) 
 The angle subtended at the eye by an object is equal to the angle subtended at the eye by the virutal image produced by a magnifying glass. In what sense then does a magnifying glass provide angular magnification?
(b) In viewing through a magnifying glass, one usually positions one’s eyes very close to the lens. Does angular magnification change if the eye is moved back ?
(c) Magnifying power of a simple microscope is inversely proportional to the focal length of the lens. What then stops us from using a convex lens of smaller and smaller focal length and achieving greater and greater magnifying power ?
(d) Why must both the objective and the eye-piece of a compound microscope have short focal lengths ?
(e) When viewing through a compound microscope, our eyes should be positioned not on the eye-piece but a short distance away from it for best viewing. Why ? How much should be that short distance between the eye and eye-piece ?
Answer:
(a) When magnifying glass is not used, object to be seen clearly is to be placed at 25 cm. However, while using magnifying glass, object can be placed closer to eye than at 25 cm. The closer object has large angular size than the same object placed at 25 cm. It is in this sense that magnifying glass provides angular magnification.
(b) Yes. The angular magnification decreases slightly because angle subtended at eye is somewhat less than the angle subtended at the lens.
(c) The aberrations like spherical and chromatic aberrations start croping up if the convex lens of smaller and smaller focal length is made.
(d) Angular magnification of eye piece is given by (1+D/fe)  and angular magnification of objective is approximately given by υ/f0. Clearly for better magnification focal length of eye piece fe and focal length of objective fe should be small.
(e) If we position our eye very close to the eyepiece, the whole light will not fall on our eye and the field of view will decrease. So we place our eye a short distance away from the eye-piece to collect the large amount of light refracted through the eyepiece to increase the field of view.

Question 33.
An angular magnification (magnifying power) of 30 X is desired using an objective of focal length 1.25 cm and eye piece of focal length 5 cm. How will you set up the compound microscope ?

Question 35.
For the telescope described in the last exercise, in 9.34
(a) what is the separation between the objective lens and the eye-piece ?
(b) If this telescope is used to view a 100 m tall tower 3 km away, what is the height of image of the tower formed by objective lens ?
(c) What is the height of final image of the tower if it is formed at 25 cm ?
Answer:
(a) Since the final image is formed at infinity, the distance between the object lens and the eye-piece is f0 + fe = 140 + 5 = 145 cm

The Making of the National Movement 1870s – 1947 Class 8 Questions and Answers History Chapter 11

History Class 8 Chapter 11 NCERT Textbook Questions and Answers

Question 1.
Imagine that you are involved in the Indian national movement. Based on your readings of this chapter, briefly discuss your preferred methods of struggle and your vision of a free India.
Answer:
I would prefer to be a member of the revolutionaries mainly Bhagat Singh and his group. Whatever they did was right and I would also do what they did. I am not a person to suffer the injustice of the British. After all we (Indian) too are human beings. We should always be ready to fight for our motherland.

Question 2.
Why were people dissatisfied with British rule in the 1870s. and 1880’s?
Answer:
People were dissatisfied with British rule in the 1870s and 1880s due to the following reasons :
1. The British passed the Arms Act in 1878 which disallowed Indians from possessing arms.
2. In the same year they passed the Vernacular Press Act. This Act snatched the freedom of speech and expression. It allowed the government to confiscate the assets of newspapers including their printing presses if the newspapers published anything that was critical of the government.
3. In 1883, the Ilbert Bill was introduced. The bill provided for the trial of British or European persons by Indian and sought equality between British and Indian Judges in the country. But the white opposition forced the government to withdraw the bill.

Question 3.
Who did the Indian National Congress wish to speak for?
Ans. The Indian National Congress did not wish to talk only on behalf of professional groups, zamindars to industrialists hue also for peasants, artisans, women and for all people of the country. It also raised a number of economic issues, social issues, and political issues.

Question 4.
What economic impact did the First World War have on India?
Answer:
The First World War led to a huge rise in the defence expenditure of the Government of India. The government in turn increased taxes on individual incomes and business profits.

Increased military expenditure and the demands for war supplies led to the sharp rise in prices which badly affected the common mass. They found it difficult to fulfil even their essential needs.

But the business groups earned huge profits from the war. The war created a demand for industrial goods like jute bags, cloth, rails and caused a decline of Import’s from other countries into India. As a result Indian industries expanded during the war.

Question 5.
What did the Muslim League resolution of 1940 ask for?
Answer:
In 1940 the Muslim League had moved a resolution demanding “Independent states” for Muslims in the north-western and eastern areas of the country. The resolution did not mention partition or Pakistan.

Question 6.
Who were the Moderates? How did they propose to struggle against British rule?
Answer:
The Moderates were against extreme actions. They had deep faith in the good intention of the government. They were of the opinion that slowly and steadily they would make the British go to their own land.

The moderate leaders developed public awareness about the unjust nature of British rule. They published news papers, wrote articles and showed how British rule was leading to the economic ruin of the country. They criticised British rule in their speeches and sent representatives to different parts of the country to mobilise public opinion. They believed that the British had respect for the ideals of freedom and justice and therefore, they would definitely accept all the just demands of the people of India. Their main task was to acknowledge the British government with these demands.

Question 7.
How was the politics of the Radicals within the Congress different from that of the Moderates?
Answer:
The radicals criticised the moderates for their “politics of prayers” and emphasised the importance of self-reliance and constructive work. They argued that people must rely on their own strength not on the “good” intentions of the government; people must fight for swaraj. Tilak raised the slogan “ Freedom is my birth right and I shall have it!”

Question 8.
Discuss the various forms that Non-cooperation Movement took in different parts of India. How did the people understand Gandhiji?
Answer:
The Non-cooperation movement spread for and wide. It took various forms in different parts of the country:

  1. In Kheda, Gujarat, Patidar peasants were worried about the high land revenue demand of the British. Hence they organised non-violent campaigns against it.
  2.  In coastal Andhra and interior Tamil Nadu, liquor shops were picketed.
  3. In the Guntur district of Andhra Pradesh, Tribals and poor peasants started several forest satyagrahas, sometimes sending their cattle into forests without paying grazing tax. They were very much fed up with the restrictions imposed on them by the British regarding the use of forest resources. They wanted the abolition of the forest regulations.
  4. In Sind, now in Pakistan, Muslim trades and peasants were very enthusiastic about the Khilafat call. In Bengal too, the khilafat Non-cooperation alliance gave enormous communal unity and strength to the national movement.
  5. In Punjab, the Akali agitation of the Sikhs sought to drive out corrupt mahants, supported by the British from the gurudwaras. This movement got closely identified with Non-cooperation movement.
  6. In Assam, tea garden labourers left with the British owned plantations and become the followers of Gandhiji.
    People viewed Gandhiji as a messiah as some one who could help them overcome their misery and poverty.

Question 9.
Why did Gandhiji choose to break the salt law?
Answer:
Gandhiji declared that he would lead a march to break the salt law. According to this law, the state had a monopoly on the manufacture and sale of salt. Mahatma Gandhi along with other nationalists reasoned that it was sinful to tax salt since it is such an essential item of our food. The salt march related the general desire of freedom to a specific grievance shored by every body, and thus did not divide the rich and the poor.

Gandhiji and his followers marched for over 240 miles from Sabarmati to the coastal town of Dandi where they broke the government law by gathering natural salt found on the seashore and bailing sea water to produce salt.

Question 10.
Discuss those developments of the 1937—47 period that led to the creation of Pakistan.
Answer:
From the late 1930, the Muslim League began viewing the Muslims as a separate- nation from the Hindus. This nation might have developed because of the history of tension between some Hindu and Muslim groups in the 1920s and 1930s The provincial elections of 1937 also might have convinced the League. The Muslims were a minority and they would always have to play fiddle frilled in any democratic structure. Meanwhile, the rejected the Legue’s desire to form a joint Congress- League government in the united provinces in 1937. This annoyed the League.

In 1940, the league finally moved a resolution demanding ‘Independent states’ for Muslim in the north-western and eastern areas of the country. The resolution
did not mention partition or Pakistan.

In 1945, the British opened negotiations between the Congress, the league and themselves for the independence of India. The talks could not succeed because the League saw itself as the sole spokesperson of India Muslims. The Congress proved this claim baseless because several Muslims still supported it.

In the provincial elections in 1946 the League got grand success in the seats reserved for Muslims. Hence it persisted its demand for Pakistan. In march 1946, the cabinet mission came to Delhi to examine this demand and to suggest a suitable political framework for a free India. This mission suggested that India should remain united and constitute itself as confederation a loose with some autonomy for Muslim-majority areas. Neither the Congress nor the Muslim League agreed to it. The failure of the cabinet mission made partition inevitable. Ultimately in 1947 partition took with the birth of a new country, i.e, Pakistan.

He is a Mahatma or sadhu, a Pundit, a Brahmin who lives at Allahabad, even a devta ………. the real power of his name is to be traced back to the idea that it was he who got bedakhli (illegal eviction) stopped in Pratapgarh ……. as being antagonistic to Government, but only to the zamindars ………… We are for Gandhiji and the Sarkar.

Markets Around Us Class 7 Questions and Answers Civics Chapter 8

Class 7 Civics Chapter 8 NCERT Textbook Questions and Answers

Question 1.
Why do people go to a weekly market? Give three reasons.
Answer:
People go to a weekly market because of the following reasons:

  1. Many things in weekly markets are available at cheaper rates.
  2. Most things that we need are available at one place.
  3. Since weekly markets have a large number of shops selling the same goods, then, things can be available at a cheaper rate.

Question 2.
Who are the sellers in a weekly market? Why don’t we find big business persons in these markets?
Answer:
The sellers in a weekly market are local people who do not have permanent shops. These small traders set up shops for the day and then close them in the evening. Then they may set up at a different place the next day.

We do not find big businessmen in these markets, because they have permanent shops in a shopping complex or mall.

Question 3.
Why are things cheap in the weekly market?
Answer:
Things are cheap in the weekly market because of the following reasons :

  1. The shops are temporary, i.e., not permanent. The shopkeepers do not have to pay rent, electricity, fees to the government, etc.
  2. The shopkeepers do not have to pay wages to their workers.
  3. Most of the things that are sold by the shopkeepers are stored at home.
  4. Most of them are helped by, their family members and, hence do not need to hire workers.

Question 4.
Explain with an example how people bargain in the market. Can you think of a situation where the bargain would be unfair?
Answer:
Weekly markets have a large number of shops selling the same goods which means there is a competition among them. If some trader were to charge a high price, for example, apples, people would move to another shop where the apples may be available more cheaply or the buyer may bargain and bring the price down.

The bargain would be unfair if the seller is selling his goods at a reasonable (cheaper) price.

Question 5.
Why did Sujata carry a notebook? Do you think this system is useful? Can there be problems?
Answer:
Sujata carried a notebook because she was buying goods on credit. It is useful as long as both buyer and seller and fair. The buyer should pay the seller the amount of the exact time without any hindrance.

Yes, this system can create problems when the buyer does not pay his dues; or the seller has forgotten to write any article sold to the buyer, etc.

Question 6.
What are the different kinds of shops that you find in your neighbourhood? What do you purchase from them?
Answer:
We find all types of shops in our neighbourhood, such as groceries, clothes, chemists, daily needs shop, fair price, vegetable and fruit shops, etc.

Normally, we purchase all the items needed from them.

Question 7.
Why are goods sold in permanent shops costlier than those sold in the weekly markets or by road side hawkers?
Answer:
Goods sold in permanent shops are costlier because these shops, incur a lot of expenditure” they have to pay rent, electricity, fees to the government, and, they also have to pay wages to their workers. More over these shops sell branched or packed goods.

Question 8.
Why do you think the guard wanted to stop Kavita and Sujata from entering the shop? What would you say if someone stops you from entering a shop in a market?
Answer:
Kavita and Sujata were wandering on the 3rd floor. The guard wanted to stop them for entering the shop because he thought that they did not have the money to buy clothes. There were just going inside to look at the clothes being sold at the shop.

If someone stops me from entering a shop in a market, I would pull his hat and remind him that everyone is free to go to any place he/she likes. It is not necessary that in whichever shop we enter, we have to buy something.

Question 9.
Why do people not bargain in shops located in malls whereas they bargain in weekly markets?
Answer:
People do not bargain in the shop located in the malls whereas they bargain in weekly market because branded goods available in the mall are expensive, durable, and often promoted by advertising, claiming of better quality as compared to non branded goods. Fewer people afford to buy but dono’t bargain in terms of quality and brand.

Question 10.
How do you think your neighbourhood shop gets its goods? Find out and explain with some examples.
Answer:
Our neighbourhood shop gets its goods through agents or wholesaler For example A vegetable wholesale trader will not buy a few kilos of vegetables, but will buy a large lot of 25 to 100 kilos.

There will be then sold to other traders. It is through this the retailer get the goods and finally reaches to our neighbourhood shop.

Question 11.
Why is a wholesale trader necessary?
Answer:
Goods are produced in factories, on farms, and in homes. However, we don’t buy directly from the factory or from the farm. The goods from factories, or farms etc. are purchased by the wholesaler and sold to the retailer.

From the retailer we buy goods. Thus, a wholesale trader is necessary.

Question 12.
In what ways is a hawker different from shop-owner?
Answer:
Hawker is a person who sells his product or goods by moving on the streets while a shop-owner is a person who sells his goods at a fixed place. A hawker can sell different goods like vegetables, clothes, shoes, etc., while shop owner sell the some things or goods. For e.g. in a book shop you can get only books, stationery etc., not vegetables, ice-cream, sweets etc.

Question 14.
Explain how a chain of markets is formed. What purpose does it serve?
Answer:
A series of markets that are connected like a link in a chain because products pass from one market to another is known as chain of market. The people in between the producer and the final consumers are the traders, middlemen agent, etc.

(a) The producer supplies goods to retailer who sell them to customers. Producer : Retailer : Customers producer: Wholesaler: Customer. The goods can be sold with the help of retailer and wholesaler in the following chain process :

NCERT Solutions for Class 7 Social Science Civics Chapter 8 Markets Around Us 3

It is through this links (chain) of the trader the goods reaches far away places. The purpose of this chain markets is to make the easiest availability of all the goods at far away place immediately.

Question 15.
All persons have equal right to visit any shop in a market place. Do you think this is true of shops with expensive products? Explain with example.
Answer:
Yes, all persons have equal rights to visit any shop in a market place. It is also true of shops with expensive products.

Example:
Kavita and Sujata are two friends. They went to Anzal Mall, a five floor shopping complex. They were enjoying themselves, then they decided to go to a branded ready made shop which was situated on 3rd floor. Security guard wanted to stop them, but he could not, they looked at some costly dresses, but none was less than 2500 Rs. Sujata whispered to Kavita, let us try on another shop. I’ll take you another shop which has good quality readymade clothes at very reasonable prices.

Question 16.
‘Buying and selling can take place without going to a market place’. Explain this with the help of examples.
Answer:
Yes, Buying and selling can take place without going to a market place. We can place order for variety of things through phone and these days through internet, and the goods are delivered at our homes.
Example :

In clinic and nursing homes we have noticed that sales representatives waiting for doctors. Such persons are also engaged in selling of goods. Thus buying and selling take . place in different ways, not necessarily through shops in the market.

Another example can be given of a Pizza Hut. The favourite Pizzahuts have toll free mobile and land-line numbers. We can place our order through phone call. Their home delivery service will drop the pizza at our doorstep within a short time. These shops run 24 hrs daily.

Why do developed countries want developing countries to liberalise their trade and investment? What do you think Should the developing countries demand in return?
Answer:
The developed countries want the developing countries to liberalise their trade and investment so that the raw-material man-power, market of the developing countries can be utilized by the MNCs of the developed nations. This helps the developed nations to fully utilize their surplus money.

The developing countries should, in return, seek fair globalisation benefits. The globalising effects should help the economy and employment avenues of the developing nations. These developing nations should seek benefits of globalization and a fair share in development of their economy.

Question 6.
“The impact of globalisation has not been uniform.” Explain this statement.
Answer:
The impact of globalisation has not been uniform. The consumers do enjoy the foreign- sponsored products, but these are only the well- off urban consumers; workers do enjoy the benefits of good salaries, but the workers outside the globalization institution, especially the rural poor have not been adequately compensated. The benefits of the globalisation efforts have been more towards the MNCs rather than the native companies.

Question 7.
How has liberalisation of trade and investment policies helped the globalisation process?
Answer:
The liberalisation of trade and investnments, indeed, helped the globalisation process. Our foreign trade has increased; private sector has contributed a lot in country’s economy; the Indians have been able to enjoy the foreign- sponsored and foreign manufactured products. The liberalising measures of the government have helped the private enterprises to produce products with quality. The Indian products are competing with the products of other countries in the international markets.

Question 8.
How does foreign trade lead to integration of markets across countries? Explain with an example other than those given here.
Answer:
Foreign trade is a trade among different nations. It helps to integrate markets across countries. What we have less, we wise to buy that, and what we have more, we wish to sell to others. For selling the products we have in plenty, we seek foreign markets to export them. For buying the products we are in shortage, we buy them from others, i.e., we import those products. In both cases we seek foreign markets and in the process, we integrate. We export textiles and import crude oil.

Question 9.
Globalisation will continue in the future. Can you imagine what the world would be like twenty years from now? give reasons for your answer.
Answer:
Globalisation is not only going to stay, it is going to continue. It is a process of future, and in fact, the only process in the future. Once having made a beginning, it has to go further and further. After 20 years from now, we will have a situation when the borders would have no meaning; one would be travelling to other countries as if one is travelling to other cities. Social, economic and cultural relations would widen and people of the world be too nearer and closer. In fact, it would, then, be a world like a global village.

Question 10.
Supposing you find two people arguing. One is saying globalisation has hurt our country’s development. The other is telling globalisation is helping India develop. How would you respond to these organisations.
Answer:
There is a lot of misinformation and misgivings about globalisation. On the one hand, it is argued that the globalisation is damaging our development in so far as we have begun depending on others. The other argument has the opposite view, i.e., we are developing because of globalization the fact of the matter is that globalisation has put us in the larger situation of the world; we are now at a ground where we have to compete with others. It is here that our skill matters; it is here that our expertise and quality matters; it is here that we face our competitors in the spirit of real competition. Globalisation provides us a challenge; v-.- need to face it and accept it.
