Two bodies have their moments of inertia...

Two bodies have their moments of inertia `I` and `2 I` respectively about their axis of rotation. If their kinetic energies of rotation are equal, their angular momenta will be in the ratio.

A

`1 : 2`

B

`sqrt2 : 1`

C

`2 : 1`

D

`1 : sqrt2`

Text Solution

Verified by Experts

`K_(R)=(L^(2))/(2I)`
`(L_(1)^(2))/(2I)=(L_(2)^(2))/(2(2I))`
`(L_(1))/(L_(2))=(1)/(sqrt2)`
