charge density fixed horizontally A neutral and smooth ring Q of mass M can slide freely on the rod which happens to just fit in it and P is a non conducting particle having a mass m and charge q attached to the ring Q by means of a non conducting and inextensible string of length R P is released from the position shown in figure when the string becomes vertical SR IIT CO SC disha Narayana IIT Academy 1800 419 1828 A dull mind gets bored easily A curious mind expands forever A The speed of the particle P is v 71 2 m R q x 1 2 1 4 2gR M fv m 04 07 21 OSR IIT CO SC JEE Adv GTA 16 P 1 Q P 9 2fv r R B The tension in the string is T mg mv R Page No 6 In 1 m M C The loss in gravitational and electrostatic potential energy of the system appears as gain in its kinetic energy
