Vedclass · Answer

(C) The ball is covered with conducting paint,making it a conductor. Initially,the ball is attracted to the high-voltage plate due to electrostatic induction. When the ball touches the high-voltage plate,it acquires some charge through conduction and is then repelled by the high-voltage plate. The ball moves towards the earthed plate. Upon touching the earthed plate,the ball transfers its charge to the earth,becoming neutral. Once neutral,it is again attracted to the high-voltage plate,and the process repeats. Thus,the ball swings backward and forward,hitting each plate in turn.

$A$ table tennis ball,which has been covered with conducting paint,is suspended by a silk thread so that it hangs between two plates. One plate is earthed,and the other is connected to a high-voltage generator. This ball:
