Question
A solid sphere rolls down an inclined plane and its velocity at the bottom is v1. Then same sphere slides down the plane (without friction) and let its velocity at the bottom be v2. Which of the following relation is correct
Answer: Option D
:
D
When solid sphere rolls down an inclined plane the velocity at bottom v1=√107gh
but, if there is no friction then it slides on inclined plane and the velocity at bottom v2=√2gh
∴v1v2=√57.
