A positive charge is uniformly distributed along a circular ring of radius R A small test charge qis placed at the centre of the ring Then q ON A If q 0 and is displaced away from the centre in the plane of the ring it will be pushed back towards the centre B If q 0 and is displaced away from the centre in the plane of the ring it will never return to the centre and will continue moving till it hits the ring C If q 0 it will perform SHM for small displacement along the axis D q at the centre of the ring is in an unstable equilibrium within the plane of the ring for q 0 E 19 36
