a ring of raduis 7 cm carries a uniform charge of -37 nc on its surface the axis of the ring is the x axis a small plastic ball with a unform chargeA) How much work does it take to move a tiny +3.00 − μC charged ball of mass 1.50 g from infinity away to the centre of the ring?B) In your solution of part A, is it necessary to move the charge +5.00μC along a path on the axis of the ring? Why?
