The angular velocity of a body changes from one revolution per 9 second to 1 revolution per second without applying any torque. The ratio of its radius of gyration in the two cases is

The angular velocity of the body changes from omega_1 to omega_2 without applying torque but by changing its M.I. The ratio of initial radius of gyration to final radius of gyration is

The angular speed of a body changes from omega_1 to omega_2 without applying a torque but due to change in its moment of inertia. The ratio of radii of gyration in the two cases is :-

The angular speed of a body changes from omega_1 to omega_2 without applying a torque but due to change in its moment of inertia. The ratio of radii of gyration in the two cases is :-

What its the number of revolution per second of revolving electron in first Bohr orbit?

The angular velocity of a body is increased from 5 rad/s to 20 rad/s, without applying a torque but by changing its moment of Inertia. What is the relation between the new radius of gyration and the initial radius of gyration?

The angular velocity of flywheel changes from 240 rpm to 120 rpm in 6 seconds. Calculate the no of revolutions it will make before coming to rest.
