Question

Assertion (A): In rolling, all points of a rigid body have the same linear velocity. Reason (R): The rotational motion does not affect the linear velocity.

Assertion (A): The velocity of a body at the bottom of an inclined plane of given height is more when it slides down the plane compared to when it is rolling down the same plane. Reason (R): In rolling down, a body acquires both kinetic energy of translation and rotation.
