The moment of inertia of a thin circular disc of mass M and radius R about any diameter is

A

`2MR^(2)`

B

`(MR^(2))/(4)`

C

`(MR^(2))/(2)`

D

`MR^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
By applying perpendicular axes theorem,

`F=ld+ld=2ld`
`F=(1)/(2)mR^(2) rArr Fd=(1)/(4)mR^(2)`
