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 is rolling down the same plane. Reason: In rolling down, a body acquires both kinetic energy of translation and rotation.
Options:
Answer:
B
Solution:
When a body slides, its entire PE is converted into KE of translation. But when it rolls down, some part of its PE is converted into its of rotation, thereby reducing its of translation and hence its linear velocity.
