For a uniform ring of mass M and radius R at its centre

For a uniform ring of mass M and radius R at its centre

A circular ring of mass M and radius R is placed in YZ plane with centre at origin. A particle of mass m is released from rest at a point x = 2R. Find the speed with which it will pass the centre of ring .

A ring of radius R is with a uniformly distributed charge Q on it .A charge q is now placed in the centre of the ring .Find the increment in tension in the ring.
