Three bodies, a ring, a solid cylinder and a solid sphere roll down the same inclined plane without slipping. They start from rest. The radii of the bodiesare identical. Which of the bodies reaches the round with maximum velocity?
Text Solution
Verified by ExpertsThe correct answer is:
C
:
According to conservation of mechanical energy,
or 
Note: It is independent of the mass of the rolling body for a ring, 
For a solid cylinder, 
For a solid sphere, 
Among the given three bodies the solid sphere has the greatest and the ring has the least velocity at the bottom of the inclined plane.
