A ring of radius R carries a uniformly distributed charge +Q. A point charge `-q` is placed on the axis of the ring at a distance 2R from the centre of the ring and released from rest. The particle executes a ismple harmonic motion along the axis of the ring.

A ring of radius R carries a uniformly distributed charge + Q. A point charge - q is placed on the axis of the ring at a distance 2R from its centre and than released. Will the charge -q execute a simple harmonic motion along the axis of the ring ?

A ring of radius R is carrying uniformly distributed charge +Q . A test charge -q_0 isplaced on its axis at a distance 2R from the centre and released. The motion of the particle on the axis will be :

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.

A non conducting ring of radius R has uniformly distributed positive chargeq. A small particle of mass m and charge -q is placed on the axis of the ring at point P and released If R gt gt x . The particle will undergo oscillations along the axis of symmerty with an angular frequency that is equal to
