The masses of two uniform discs are in the ratio `1 : 2` and their diameters in the ratio `2 : 1`. The ratio of their moment, of inertia about the axis passing through their respective centres and perpendicular to their planes is

A

`1:1`

B

`1:2`

C

`2:1`

D

`1:4`

Text Solution

Verified by Experts

The correct Answer is:
C

`(I_(1))/(I_(2))=(1/2xx1xx2xx2)/(1/2xx2xx1xx1)=2/1`
