Question

A solid sphere and a hollow sphere of same mass and radius are rolled down on an inclined plane. What will be the ratio of acceleration when both reached at bottom?

Answer 1

Explanation:

mass=m

intial height = h

gravity =g

final velocity =v

radius=r

anglur velocity =w,v/r

moment of interia=kmsquare

v=root of 2gh/1+k

as hollow cylinder is slowest as it has edge which may increase mass of cylinder
