.

A

Moment of inertia of the system is minimum about `EG`

B

Momemt of inertia of the system is maximum about `HF`

C

Moment of inertia of the system is minimum about `HF`,

D

Moment of inertia of the system is maximum about `FG`

Text Solution

Verified by Experts

The correct Answer is:
A

Moment of ineria is maximum if masses are farther from the axis and vice-versa
`F_(act)=0` and `tau_(n et)=0`
