A thin circular ring of mass M and radius R is rotating in a horizontal plane about an axis vertical to its plane with a constant angular velocity omega . If two objects each of mass m be attached gently to the opposite ends of a diameter of the ring, the ring will then rotate with an angular velocity:

A disc of moment of inertia la is rotating in a horizontal plane about its symmetry axis with constant angular speed co. Another discinitially at rest of moment of inertia I, is dropped coaxially on to the rotating disc. Then, both the discs rotate with same constant angular speed The loss of kinetic energy due to friction in this process is,

If E is a rotational kinetic energy then angular momentum is

A particle of mass (m) is moving with constant velocity (v). Show that its angular momentum about any point renains constant throughout the motion.

A mass is whirled in a circular path with constant angular velocity and its angular momentum is L. If the string is now halved keeping the angular velocity the same, the angular momentum is

The relation between Rotation Kinetic Energy and angular momentum is

Two particles of mass m each are attached to a light rod of length d, one at its centre and the other at a free end, The rod is fixed at the other end and is rotated in a plane at an angular speed omega . Calculate the angular momentum of the particle at the end with respect to the particle at the centre
