(i) A person sits near the edge of a circular platform revolving with a uniform angualr speed. What will be the change in the motion of the platform ?
(ii) What if the person stars moving from the edge towards the centre of the platform ?

A person is standing on the edge of a circular platform, which is moving with constant angular speed about an axis passing through its centre and perpendicular to the plane of platform. If person is moving along any radius towards axis of rotation then the angular velocity will:

A person is sitting near the edge fo a rotating platfrom when he walks towards the centere, then:

A person sitting in the compartment of a tarin moving with unifrom speed throws a ball in the upward direction . What path of the ball will appear to him ? What to a person standing outside ?

A train goes past a person standing at the edge of a platform at high speed. Then the person will be

A person of 80 kg mass is standing on the rim of a circular platform of mass 200 kg rotating about its axis at 5 revolutions per minute (rpm). The person now starts moving towards the centre of the platform. What will be the rotational speed (in rpm) of the platform when the person reaches its centre___________.

A person of mass m stands at the edge of a circular platform of radius R and moment of inertia. A platform is at rest initially. But the platform rotate when the person jumps off from the platform tangentially with velocity u with respect to platfrom. Determine the angular velocity of the platform.

Suppose a person of mass m stands at the edge of a circular platform of radius R and moment of inertia I . The platform is at rest initially, but the platform begins to rotate when the person begins to move with velocity v . Determine the angular velocity of the platform.

If a charged particle having charge q is moving in a circular path of radius R with a uniform speed u, what would be the magnetic field at the centre?
