A body of mass m and radius r is rotated with angular velocity `omega` as shown in the figure & kept on a surface that has sufficient friction then the body will move

If a body of mass 'm' and radius of gyration K rotates with angular velocity omega , then the angular momentum of the body will be

A body of mass 'm' and radius of gyration 'K' is rotating with angular acceleration a. Then the torque acting on the body is

A ring of mass m and radius R is being rotated about its axis with angular velocity omega . If a increases then tension in ring

A ring of radius R is first rotated with an angular velocity omega and then carefully placed on a rough horizontal surface. The coefficient of friction between the surface and the ring is mu . Time after which its angular speed is reduced to half is
