Answer Key : (b) -

(b)

The cylinder is having a fixed axis, so it can perform rotational motion only

For no slipping,

 acceleration of the platform

For the maximum torque,  would be maximum and

So the maximum torque,



Next Question :

The first ball of mass  moving with a velocity  collides head on with the second ball of mass  at rest. If the coefficient of restitution is ,then the ratio of  the velocities of the first and the second ball after the collision is

a)

b)

c)

d)
