A dancer is standing on a rotating platform taking two sphere on her hands. If she drops down the sphere on ground, then dancer's:

A person is standing on a rotating table with metal spheres in his hands. If he withdraws his hands to his chest, then the effect on his angular velocity will be.

A person standing on a rotating platform with his hands lowered, outstretches his arms. The angular momentum of the person

(A) : A person standing on a rotating platform suddenly stretcehed his arms, the platform slows down. (R ) : In case of person on a rotating platform angular momentum is constant.

A dancer is standing on a stool rotating about the vertical axis passing through its centre. She pulls her arms towards the body reducing her moment of inertia by a factor of n. The new angular speed of turn table is proportional to
