The angular velocity of the body changes...

The angular velocity of the body changes from `omega_1` to `omega_2` without applying torque but by changing its M.I. The ratio of initial radius of gyration to final radius of gyration is

A

`omega_2: omega_1`

B

`omega_2 ^(1//2) : omega_1^(1//2)`

C

`omega_2^2 : omega_1^2`

D

`1/omega_2 : 1/omega_1`
