1.	A thin rotates about an axis passing through its centre and perpendicular to its plane with a constant angularvelocity .omega. I is the moment of inertia of that discand .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)
