A disc and a sphere of same radius but different masses roll off on two inclined planes of the same altitude and length. Which one of the two objects gets to the bottom of the plane first?
Text Solution
Verified by ExpertsThe correct answer is:
D
: Time taken by the body to reach the bottom when it rolls down on an inclined plane without slipping is given by
Since 
is constant and 
and 
are same for both
Hence, the sphere gets to the bottom first.
