1 Motion of System of Particles and Rigid Body

A reference frame attached to the Earth

1) is an inertial frame by definition.
2) is an inertial frame because Newton's laws of motion are applicable inside it.
3) is not an inertial frame because the Earth moves with respect to the Sun.
4) cannot be an inertial frame of reference because of the Earth's rotation and revolution.

Option 1

Option 2

Option 3

Option 4 Solution:

An inertial frame of reference is one which has a constant velocity and no acceleration. Because of the Earth's rotation and revolution, the direction of motion keeps changing and therefore the velocity is not constant. Hence this is not an inertial frame of reference.

2 Kinetic Theory of gases

In a closed container the mass of molecule is 3 x 10^-27 kg. and velocity of molecule is 10 m/sec. If the no. of molecules in the container is 10²⁴, the pressure will be :

(1) 100 N/m²
(2) 10 N/m²
(3) 1 N/m²
(4) 0.5 N/m²

Option 4

3 Work Energy and Power

Two marbles, one twice as heavy as the other, are dropped to the ground from the roof of a building. Just before hitting the ground, the heavier marble has:

1. Twice as much kinetic energy as the lighter one.

2. The same kinetic energy as the lighter one.

3. Four times as much kinetic energy as the lighter one.

4. Half as much kinetic energy as the lighter one.

6 Work Energy and Power

A bob is suspended from a crane by a cable of length l = 5m. The crane and load are moving at a constant speed v. the crane is stopped by a bumper and the bob on the cable swings out an angle of 60°. The initial speed v is ( g=9.8 m/s²)

1) 10 m/s
2) 7 m/s
3) 4 m/s
4) 2 m/s

Option 1

Option 2 Solution:

Solution

Change in kinetic energy=potential energy of bob
½ mv2=mgl(1 - cos60)

Option 3

Option 4

7 Wave Optics

The two slits at a distance of 1 mm are illuminated by the light of wavelength $$ 6.5 \times 10^{-7} m $$. The interference fringes are observed on a screen placed at a distance of 1 m. The distance between third dark fringe and fifth bright fringe will be:

1) 0.65 cm
2) 4.8 mm
3) 1.62 mm
4) 3.25 cm

Option 1

Option 2

Option 3 Solution:

Solution

For dark Fringe,

$$x= \displaystyle \frac{(2n-1) \lambda D}{2d}$$
$$X_3 = \displaystyle \frac{(2 \times 3 -1 ) \times 6.5 \times 10^{-7} m \times 1 m}{2 \times 10^{-3} m}$$

$$x_3 = 1.63 \times 10^{-3} m$$
For bright Fringe

$$x = \displaystyle \frac{n \lambda D}{d}$$

$$ \therefore X_5 = \displaystyle \frac{5 \times 6.5 \times 10^{}-7 m \times 1m}{10^{-3} m}$$

$$x_5 = 3.25 \times 10^{-3} m$$
Distance between third dark fringe and fifth bright fringe = $$(x_5 - x_3) = 1.62 mm$$

Option 4

8 Physical world and measurement

Consider the following statements about dimensions :

P: Force = acceleration due to gravity x mass

Q :Electric charge = current x time

R : Magnetic flux = Electric voltage x time

The correct statements are:

(1) R, P only
(2) P, Q and R
(3) P, Q only
(4) Q, R only

Option 1

Option 2

Option 3 Solution:

Option 4

(1) 1 : 4 (2) 4: 1

(3) 1: 2 (4) 2 : 1

Option 1

Option 2

Option 3

Option 4 Solution:

10 Electromagnetic Induction

The self inductance of a coil having 400 turns is 10 mH. The magnetic flux through the cross section of the coil corresponding to Current 2 mA is

1) 4×10⁻⁵ Wb
2) 2×10⁻³ Wb
3) 3×10⁻⁵ Wb
4) 8×10⁻³ Wb

Option 1 Solution:

Solution

Here, $$N = 400, L = 10 mH = 10 \, \times \, 10^{-3}H
I = 2 mA = 2 \, \times \, 10^{-3}A$$
total magnetic flux with the coil,
$$\phi = NLI = 400 \, \times \, (10 \, \times \, 10^{-3})\, \times \, 2 \, \times \, 10^{-3} = 8 \, \times \,10^{-3}SWb$$
Magnetic flux through the cross - section of the coil
= Magnetic flux linked with each turn
=$$\dfrac{\phi }{N} \, = \, \dfrac{8 \times 10^{-3}}{200} \, = \, 4 \times 10^{-5}Wb$$
