A ring of radius R is charged uniformly with a charge `+Q`. The potential at a point on its axis at a distance 'r' from any point on ring will be-

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 uniformly charged by + Q charge. Find potential at an axial point, which is situated at distance r from the centre and hence deduce electric field.

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 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 simple harmonic motion along the axis of the ring. State True or False.
