A disc of moment of inertia I is rotating in horizontal plane about an axis passing through a centre and perpendicular to its plane with constant angular speed o Another disc of moment of inertia 1 having zero angular speed is placed coaxially on a rotating disc Now both the discs are rotating with constant angular speed The energy lost by the initial rotating disc is 2 1 1 1 1 2 00 B 11207 2 1 1 11 22 2 11 2 007 D 2 1 1 I I 00
