τ= 30 X 1 x 6 x n (8 X 10^-2)² sin 60
= 180 x it (8 x 10-²)² 0.866
= 3.13 N m
The magnitude of the counter torque is 3 .13 N m
(b) Answer will not change because torque does not depend upon shape of the coil provided it encloses same area.

Question 14.
Two concentric circular coils X and Y of radii 16 cm and 10 cm, respectively, lie in the same vertical plane containing the north to south direction. Coil X has 20 turns and carries a current of 16 A : coil Y has 25 turns and carries a current of 18 A.

Question 15.
A magnetic field of 100 G (1 G = 10^-4 T) is required which is uniform in a region of linear dimension about 10 cm and area of cross-section about 10^-3 m². The maximum current-carrying capacity of a given coil of wire is 15 A and the number of turns per unit length that can be wound round a core is at most 1000 turns m^-1. Suggest some appropriate design particulars of a solenoid for the required purpose. Assume the core is not ferromagnetic.
Answer:

Show that the field on the axis around the mid-point between the coils is uniform over a distance that is small as compared to R, and is given by,

(Such an arrangement to produce a nearly uniform magnetic field over a small region is known as Helmholtz coils.)
Answer:

(b) Let there be two coils as mentioned in the statement. Magnetic field in a small region of length 2d about the mid-point of the space between the two coils is given by,

Question 17.
A toroid has a core (non-ferromagnetic) of inner radius 25 cm and outer radius 26 cm, around which 3500 turns of a wire are wound. If the current in the wire is 11 A, what is the magnetic field (i) outside the toroid, (ii) inside the core of the toroid, and (iii) in the empty space surrounded by the toroid.
Answer:
(i) Zero

Question 18.
Answer the following questions :
(a) A magnetic field that varies in magnitude from point to point but has a constant direction (east to west) is set up in a chamber. A charged particle enters the chamber and travels undeflected along a straight path with constant speed. What can you say about the initial velocity of the particle ?

(b) A charged particle enters an environment of a strong and non-uniform magnetic field varying from point to point both in magnitude and direction, and comes out of it following a complicated trajectory. Would its final speed equal the initial speed if it suffered no collisions with the environment ?

(c) An electron travelling west to east enters a chamber having a uniform electrostatic field in north to south direction. Specify the direction in which a uniform magnetic field should be set up to prevent the electron from deflection from its straight line path.
Ans.
(a) The particle goes undeflected so it does not experience magnetic force.
Using F = qυ B sin θ. It is clear that the initial velocity u is either parallel or anti-parallel to magnetic field (B) i.e. θ is either 0° or 180°.

(b) Yes. the final speed is equal to the initial speed because the magnetic force can change the direction of o but the magnitude of o can not be changed by it.

(c) Force acting on electron due to electrostatic field ( E→ ),
F→_e =-eE→

The direction of this force is towards North. Therefore, electron is deflected towards North. Force acting on electron due to magnetic field, F→_m= -e v→ xB→. The electron will not be deflected and move in a straight line path, if the force due to magnetic field on the electron is towards South. According to Fleming’s left hand rule, the direction of B→ is along the vertical in downward direction.

Question 19.
An electron emitted by a heated cathode and accelerated through a potential difference of 2.0 kV, enters a region with uniform magnetic field of 0.15 T. Determine the trajectory of the electron if the field (a) is transverse to its initial velocity, (b) makes an angle of 30° with the initial velocity.
Answer:
K.E, acquired by electron while passing through V

(b) When electron moves with velocity r making an angle of 30° with the direction of magnetic field, then r cos θ is

Question 20.
A magnetic field set up using Helmholtz coils (described in Exercise 4.16) is uniform in a small region and has a magnitude of 0.75 T. In the same region, a uniform electrostatic field is maintained in a direction normal to the common axis of the coils. A narrow beam of (single species) charged particles all accelerated through 15 kV enters this region in a direction perpendicular to both the axis of the coils and the electrostatic field. If the beam remains undeflected when the electrostatic field is 9.0 x 10⁵ V m^-1, make a simple guess as to what the beam contains. Why is the answer not unique.
Answer:

The given particle may be deutron.
The result is not unique because this e/m ratio can be true for He^{+ +} , Li ^{+ + +} etc.

Question 21.
A straight horizontal conducting rod of length 0.45 m and mass 60 g is suspended by two vertical wires at its ends. A current of 5.0 A is set up in the rod through the wires.”
(a) What magnetic field should be set up normal to the conductor in order that the tension in the wires is zero ?
(b) What will be the total tension in the wires if the direction of current is reversed keeping the magnetic field same as before ? (Ignore the mass of the wires.) g = 9.8 ms^-2.
Answer:
(a) The tension in the wire is zero if force on the current carrying wire due to current is equal and opposite to the weight of the wire. This is, BIl= mg

(b) In case current is reversed, the tension is equal to the force acting on the wire due to magnetic field plus weight of the wire. This is,
T = BlL + mg
= 0.26 x 5 x 0.45 + 60 x 10^-3 x 9.8
= 1.18 N.

Question 22.
The wires which connect the battery of an automobile to its starting motor carry a current of 300 A (for a short time). What is the force per unit length between the wires if they are 70 cm long and 1.5 cm apart ? Is the force attractive or repulsive (H.S.E.B.2001)
Answer:

Since the currents in two wires are in opposite direction so the force is repulsive.

Question 23.
A uniform magnetic field of 1.5 T exists in a cylindrical region of radius 10.0 cm, its direction parallel to the axis along east to west. A wire carrying current of 7.0 A in the north to south direction passes through this region. What is the magnitude and direction of the force on the wire if,
(a) the wire intersects the axis,
(b) the wire is turned from N-S to northeast-northwest direction.
(c) the wire in the N-S direction is lowered from the axis by a distance of 6.0 cm ?
Answer:

Question 24.
A uniform magnetic field of 3000 G is established along the positive z-direction. A rectangular loop of sides 10 cm and 5 cm carries a current of 12 A. What is the torque on the loop in the different cases shown in Figure? What is the force on each case ? Which case corresponds to stable equilibrium ?

Answer:

Question 25.
A circular coil of 20 turns and radius 10 cm is placed in a uniform magnetic field of 0.10 T normal to the plane of the coil. If the current in the coil is 5.0 A, what is the
(a) total torque on the coil,
(b) total force on the coil,
(c) average force on each electron in the coil due to the magnetic field ?
(The coil is made of copper wire of cross-sectional area 10^-5 m², and the free electron density in copper is given to be about 10²⁹ m³)
Answer:

Question 26.
A solenoid 60 cm long and of radius 4.0 cm has 3 layers of windings of 300 turns each. A 2.0 cm long wire of mass 2.5 g lies inside the solenoid (near its center) normal to its
axis ; both the wire and the axis of the solenoid are in the horizontal plane. The wire is connected through two leads parallel to the axis of the solenoid to an external battery which supplies a current of 6.0 A in the wire. What value of current (with appropriate sense of circulation) in the windings of the solenoid can support the weight of the wire ? g = 9.8 ms^-2.
Answer:

Question 27.
A galvanometer coil has a resistance of 12 Q and the meter shows full scale deflection for a current of 3 mA. How will you convert the meter into a voltmeter of range 0 to 18 V ?

Clouds are formed when the process of evaporation takes place by turning water into vapour which rises and leads to the formation of clouds.
Rain can sometimes be severely heavy, such as on a stormy day when there are thunder and lightning as well.
Very heavy rain is capable of causing a lot of destruction, by creating floods or by toppling trees, light poles and even buildings.
Rain can also be very light and mild, where you may not even be able to tell that it is raining, at times.
Rain can also come in the form of hail, which refers to small pieces of frozen rain (ice) which can hurt if they hit the head.
Snow is also a form of precipitation which falls in the form of ice crystals, which are different from frozen ice or hail.
A good level of rainfall is necessary for crops to grow properly and for them to be well-nourished.
Rainfall is also important for all living beings, as we all are made up mostly of water, among other things.

Clouds are formed as part of the water cycle of the earth, where water turns into water vapour and through the process of evaporation, goes into the sky and turns into clouds, which then fall as rain.
Rain is incredibly important to keep the hydrological balance of the earth in check, as it carries on the water cycle as it continues from the sky to earth.
Rain is very essential to the growth of crops and the cultivation of agriculture and its allied activities, such as horticulture and floriculture.

It usually rains the most in the monsoon season, which is usually right after the summer months, and it rains much more heavily in tropical areas than anywhere else.
It is important for cities to have appropriate rainwater drainage and rainwater harvesting systems in place to ensure that it is being treated properly and is also being saved wherever it can be saved.
It can be fun to play in the rain, but one may also get sick doing so, thus, it is important to stay safe when it rains and be sure to always carry an umbrella with you.

Frequently Asked Questions on Rain

Question 1.
Which are the monsoon months?

Answer:
Monsoon is the season in which the highest amount of rain occurs, especially in the tropical areas of the earth. The monsoon months generally follow the hot summer months of March to May, thus monsoons usually occur from the months of June to September. In some places, they may even resume in the winter months.

Question 2.
What is rainwater harvesting?

Answer:
Rainwater harvesting refers to the collection of rainwater in a huge reservoir tank, for utilisation later. This was an idea that was introduced in order to curb water pollution and also battle the problem of shortages of water, by utilising the rainwater rather than letting it all go to waste.

Question 3.
What are cyclones and hurricanes?

Answer:
Cyclones and hurricanes are two kinds of rainstorms which are quite similar. When there is low pressure in the atmosphere, the winds begin to move in a circular fashion which moves in an anti-clockwise direction from the northern to the southern hemisphere of the earth. This creates an anti-clockwise circular pattern in the water, too, along with strong winds and heavy rainfall, which is called a cyclone. A hurricane is also known as a tropical cyclone, and the difference between cyclones and hurricanes is only their geographical location. Cyclones usually start in the northern Indian Ocean, while hurricanes start in the Atlantic Ocean and the northern Pacific Ocean.

Question 4.
Where does rain come from?

Answer:
Rain is a result of the water cycle. Evaporation and condensation are two processes through which water turns into water vapour and travels skywards. Several water vapour droplets join to create one cloud, and when that cloud becomes too heavy, and gravity starts pulling on the cloud, the vapour begins to drop back down the earth in the form of rain. Thus, rain falls in the form of droplets known as raindrops.
