The moment of inertia of a copper disc, ...

The moment of inertia of a copper disc, rotating about an axis passing through its centre and perpendicular to its plane

A

increases if its temperature is increased

B

changes if its axis of rotation is changed

C

increases if its angular velocity is increased

D

both (a) and (b) are correct

Text Solution

Verified by Experts

The correct Answer is:
D
M.I. changes with changes in temperature and axis of rotation. Thus both (a) and (b) are correct.
As `I=MR^(2)` if does not depend upon `omega.`
