the parallel plate capacitor AB shown in the fig. has vertical plates, a capacitance of 4pf and a plate separation of 50mm. a small conducting ball hangs on a NON CONDUCTING THREAD of length 100mm attatched to plate A. the ball of mass 0.1gm and capacitance 0.33pf initially touches plate A. plate B is grounded while plateA is connected to a power supply of potential v for a short time by closing the switch S and then opening it again.due to this the ball now swings across , touches plate B, swing back, touches A and finally swings out again so that it almost touches plate B.
