We have two spheres, one of which is hollow and the other solid. They have identical massses and moment of intertia about theur respective diameters. The ratio of their radius is given by.

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
( c) `I_h = I_s rArr (2)/(3) MR_h^2 = (2)/(5) MR_s^2 rArr (R_h)/(R_s) = (sqrt(3))/(sqrt(5))`.
