Figure shows a very long smooth non conducting rod of radius r charged with uniform charge density fixed horizontally A neutral and smooth ring B of mass M can slide freely on the rod which happens to just fit in it A is a nonconducting particle having mass m and charge q attached to the ring by means of a non conducting and inextensible string of length R If P is released from the position shown in figure then answer the following questions The loss in electrostatic potential energy when string becomes vertical is R A q2 n 41 q 27 R q n 1 B C n 1 2r in 1 D
