Two rotating bodies have same angular momentum but their moments of inertia are I1 and I2 respectively `(I_1 gt I_2)`. Which body will have higher kinetic energy of rotation :-

Explanation

As we know `L=I omega`
`K.E. =1//2 L^(2)//I`
For same L, we can say K.E `prop 1//I`
As moment of inertia of X is greater than that of Y. Therefore, rotational kinetic energy of Y will be greater than that of X.
