### Sample Questions

Question 1
A pulley of radius 2 m is rotated about its axisby a force F = (20t – 5t2) Newton (where t is measured in seconds) applied tangentially. If the moment of inertia of the pulley about its axis of rotation is 10 kg m2, the number of rotations make by the pulley before its direction of motion if reversed, is
 more than 6 but less than 9 more than 9 more than 3 but less than 6 less than 3
Question 2
Direction : The question has Statement – 1 and Statement– 2. Of the four choices given after the statements, choose the one that describes the two statements. Statement – 1 : A metallic surface is irradiated by a monochromatic light of frequency v > v0(the threshold frequency). The maximum kinetic energy and the stopping potential are Kmax and V0 respectively. If the frequency incident on the surface is doubled, both the K max and V0 are also doubled.Statement – 2 :The maximum kinetic energy and the stopping potential of photoelectrons emitted from a surface are linearly dependent on the frequencyof incident light.
 Statement – 1 is True, Statement – 2 isTrue; Statement – 2 is a correctexplanation for Statement – 1. Statement – 1 is True, Statement – 2 isTrue; Statement – 2 is not the correctexplanation for Statement – 1 Statement – 1 is False, Statement – 2 isTrue. Statement – 1 is True, Statement – 2 isFalse.
Question 3
A mass m hangs with the help of a string wrapped around a pulley on a frictionless bearing. The pulley has mass m and radius R.Assuming pulley to be a perfect uniform circular disc, the acceleration of the mass m, if the string does not slip on the pulley, is
 3/2 g 2/3 g g g/3
Question 4
Direction :The question has Statement – 1 andStatement– 2 . Of the four choices given after the statements, choose the one that describes the two statements. Statement – 1 :Sky wave signals are used for long distance radio communication. These signals are in general, less stable than ground wave signals. Statement – 2 :The state of ionosphere varies from hour to hour, day to day and season to season
 Statement – 1 is False, Statement – 2 isTrue Statement – 1 is True, Statement – 2 isTrue; Statement – 2 is a correct explanation for Statement – 1 Statement – 1 is True, Statement – 2 is True; Statement – 2 is not the correct explanation for Statement – 1 Statement – 1 is True, Statement – 2 is False
Question 5
A screw gauge gives the following reading when used to measure the diameter of a wire. Main scale reading : 9 mm Circular scale reading : 52 divisions Given that 1 mm on main scale corresponds to 100 divisions of the circular scale.The diameter of wire from the above data is
 0.052 cm 0.52 cm 0.026 cm 0.005 cm
Question 6
Direction : The question has a paragraph followed by two statements, Statement – 1 and Statement – 2 .Of the given four alternatives after the statements, choose the one that describes the statements.A thin air film is formed by putting the convex surface of a plane–convex lens over a plane glass plate. With monochromatic light, this film gives an interference pattern due to light reflected from the top (convex) surface and the bottom (glass plate) surface of the film. Statement – 1 : When light reflects from the air–glass plate interface, the reflected wave surfers a phase change of π. Statement – 2 : The centre of the interference pattern is dark.
 Statement – 1 is False, Statement – 2 isTrue Statement – 1 is True, Statement – 2 isTrue; Statement – 2 is a correctexplanation for Statement – 1. Statement – 1 is True, Statement – 2 isFalse. Statement – 1 is True, Statement – 2 isTrue; Statement – 2 is not the correctexplanation for Statement – 1
Question 7
Two particles are executing simple harmonic motion of the same amplitude A and frequency ω along the x–axis. Their mean position is separated by distance X0(X0 > A). If the maximum separation between them is (X0 + A),the phase difference between their motion is
 π/4 π/2 π/3 π/5
X
