A thin rotates about an axis passing through its centre and perpendicular to its plane with a constant angular velocity .omega. I is the moment of inertia of that disc and .L. is its angular momentum about the given axis. Then rotational kinetic energy of the disc .E. is (A) E alpha L^(2) (B) E alpha L^(-2) (C ) E alpha I (D) E alpha I^(-1) (if L constant)

(A) : When there is no external torque moment of inertia of a rotating body changes, its angular momentum remain conserved, but its kinetic energy changes. (R ) : Angular momentum does not depend upon moment of inertia of the body.
