A uniform thin rod is bent in the form of closed loop `ABCDEFA` as shown in the figure. The ratio of moment of inertia of the loop about `x`-axis to that about `y`-axis is

A

`gt1`

B

`lt1`

C

`=1`

D

`1//2`

Text Solution

Verified by Experts

The correct Answer is:

B

Moment of inertia of semicirular portions about `x` and `y` axes are same. But moment of inertia of straight portions about `x`-axis is zero.
`:. I_(x)ltI_(y)` or `(I_(x))/(I_(y))lt1`
