It is known that point charges of the same sign repel. Can two charged bodies be attracted by the action of electrical forces? If so, in what case? Justify the answer. (Hint: Will an uncharged metal ball be attracted to a positively charged ball? Will the metal ball still attract if a positive charge much less than the ball’s charge is applied to it?)
Two similarly charged bodies can be attracted to each other if the charge of one body is much larger than the other and there is a small distance between them. Due to electrostatic induction, the amount of the induced charge can be greater than the charge of the body.
