A body is rotating with angular momentum \( L \). If I is its moment of inertia about the axis of rotation, its kinetic energy of rotation is :-
(1) \( \frac{1}{2} \mathrm{IL}^{2} \)
(2) \( \frac{1}{2} \mathrm{IL} \)
(3) \( \frac{1}{2}\left(\mathrm{I}^{2} / \mathrm{L}\right) \)
(4) \( \frac{\mathrm{L}^{2}}{2 \mathrm{I}} \)
\( \mathrm{P} \)
