Question
If a ring, a disc, a solid sphere and a cylinder of same radius rolls down on inclined plane, the first one to reach the bottom will be : -
Options
A.disc
B.ring
C.solid sphere
D.cylinder
Solution
⇒ a = time ; 
⇒ For solid sphere which is minimum in all of them.
So a is maximum and time to reach bottom is minimum.
