The plate which connected to high voltage generator induces negative charge on ball which causes attraction. When the ball strikes the positive plate, charge distribution again takes place that is the bass becomes positive and repulsion takes place. When it strikes the plate which connected to earth than its charge goes to earth and again it will be attracted towards positive plate. Hence the ball swings backward and forward hitting each plate in turn.

And forward between the two plates

The correct answer is b) Is attracted to the high voltage plate and stays there. The charges on the ball will be attracted to the opposite charges on the high voltage plate, causing the ball to move towards it and stick to it due to the electrostatic force of attraction.
