Assertion :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 rolls down the same plane. Reason: In rolling down, a body acquires both kinetic energy of translation and rotation.

Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
In sliding down, the entire potential energy is converted into kinetic energy. While in rolling down, some part of the potential energy is converted into kinetic energy of rotation. Therefore linear velocity acquired is less.
