We have a solid sphere and a very thin spheical shell their masses and moments of inertia about a diameter are same. The ratio of their radii will be :

A

`5:7`

B

`3:5`

C

`sqrt(3):sqrt(5)`

D

`sqrt(3):sqrt(7)`

Text Solution

Verified by Experts

The correct Answer is:
C
`2/3MR_(h)^(2)=2/5MR_(S)^(2)` or `(R_(h)^(2))/(R_(S)^(2))=3/5` or `(R_(h))/(R_(s))=sqrt(3/5)`
