Four small objects each of mass m are fixed at the corners of a rectangular wire-frame of negligible mass and of sides a and b (a > b) . If the wire frame is now rotated about an axis passing along the side of length then the moment of inertia of the system for this axis of rotation is:

A

`2ma^(2)`

B

`4ma^(2)`

C

`2m(a^(2)+b^(2))`

D

`2m(a^(2)-b^(2))`

Text Solution

Verified by Experts

The correct Answer is:
C
`I= 2ma^(2) + 2mb^(2)`
`=2m (a^(2) + b^(2))`
