Two oppositely charged balls A and B attract third conducting ball C when placed near them turn by turn. Then ball C must be______________?
Correct answer: B. electrically neutral
- A. positively charged
- B. electrically neutral

A neutral conducting ball is attracted to either charged ball because charges are induced within it, with the nearer opposite charge producing the stronger attraction. Thus C need not initially carry positive or negative charge.
