A point charge +q is fixed at point A on the circumference of a fixed smooth non-conducting circular wire track of radius R in a gravity free space. A small ring of mass m and charge +q which can slide freely on the wire track is given tangential velocity at point B which is diametrically opposite to A. If the distance of closest approach between the fixed charge and the ring is R then force applied by the wire track on the ring just after the release will be [F=14πϵ0q2R2] |
