Two rigid bodies with their moments of inertia in the ratio `2:3` have same rotational kinetic energy . Then ratio of their angular momenta is

A

`2:3`

B

`3:2`

C

`sqrt2: sqrt3`

D

`sqrt3: sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
C
`K.E. = (L^(2))/(2I) therefore L alpha sqrt(I) therefore (L_(1))/(L_(2))=(sqrt(2))/(sqrt(3))`.
