A positive charge Q is uniformly distributed along a circular ring of radius R A small test charge q is placed at the center of the ring then R q Z Q i If q 0 and is displaced away from the center in the plane of the ring it will be pushed back towards the centre ii If q 0 and is displaced away from the centre in a plane of the ring it will never return to the centre and will continue moving till it hits the ring iii If q 0 it will perform SHM for small displacement along the axis iv q at the centre of the ring is in an unstable equilibrium within the plane of the ring for q 0 Mark the correct option A i and iv are correct B ii and iii are correct C all are correct
