A bead of mass m and charge q is threaded on a smooth wire kept along x axis A second charge Q is fixed at the point x 0 y d It is projected with high speed so that it is initially near x and it ends up near x 00 As the moving charge passes the stationary charge find the impulse exerted by the wire on the bead Neglect gravity and assume the speed to be constant A B qQ 2 vd qQ 4 vd C qQ Evd D 2qQ Evd
