A hollow conductor is positively charged.A small uncharged metal ball is lowered by a silk thread through a small opening in the top of the conductor and allowed to touch its inner surface.After the ball is removed, it will have:

Question

Quizplus · Accepted Answer

When the small uncharged metal ball touches the inner surface of the positively charged conductor, electrons from the conductor are transferred to the ball, leaving the inner surface with a slightly negative charge due to loss of electrons. However, once the ball is removed, any charge that was transferred to it will distribute evenly across its surface and will not result in a significant charge imbalance. Therefore, the ball will have no appreciable charge.
