PhysicsSystems of Particles and Rotational MotionJEE Main

**Statement I:** 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. **Statement II:** In rolling down, a body acquires both kinetic energy of translation and rotation.

Answer: (A)

Solution

When sliding down (frictionless), all the gravitational PE converts to translational KE, giving the maximum possible speed. When rolling down, some of the PE goes into
