Bodies A and B have opposite charges. Determine which of the bodies is positively

Bodies A and B have opposite charges. Determine which of the bodies is positively charged if it is known that the positive charge placed between them moves towards the body B.

There is a rule that unlike charges attract, and like charges repel. Thus, positive charges are attracted to negative ones and repelled from positive ones. If a positive charge moves towards body “B”, then body “B” is negatively charged. Since the bodies “A” and “B” have charges of the opposite sign, and the body “B” is negatively charged, it means that the body “A” is positively charged. Answer. The body “A” has a positive charge.
