A point charge q is fixed at point A on the circumference of a fixed smooth non conducting circular wire 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 3 3F 4 5F 4 2 1 q 4 o R 2 F 4 4 F
