A hollow sphere and a solid sphere having same mass and same radii are rolled down (without sliding) a rough inclined plane.
Text Solution
Verified by ExpertsThe correct answer is:
B
a = 
For solid sphere ⇒ I cm = 
mk 2
k s = 
For hollow sphere = 
mR 2 = mk 2
k H = 
so k s < k H
then a s > a H
(so speed of solid sphere is greater then hollow sphere)
