Question

Assertion (A): A body can rotate even if its center of mass remains at rest. Reason (R): Torque causes rotational motion, independent of translational motion.

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.
