If a solid sphere and solid cylinder of ...

If a solid sphere and solid cylinder of same mass and radius rotate about their own axis the M.I. will be greater for

A

solid sphere

B

solid cylinder

C

both a and b

D

equal both

Text Solution

Verified by Experts

The correct Answer is:
B
Moment of inertia of a solid sphere `I_(s)=2/5 MR^(2)`
`I_(S)=0.4MR^(2)`
Moment of inertia of a solid cylinder `I_(C)=1/2MR^(2)`
`I_(C)=0.5MR^(2)`
We know that `I_(C)gtI_(S)`
`:.` Moment of inertia will be greater for solid cylinder.
