Object A has a negative charge. Object A is repelled by object B. Object B is repelled by object C and attracted to object D. What are the charges on objects B, C, & D?

B negatively charged. C negatively charged. D positively charged.

Explanation:

If A Is negative and B is repelled by it this means that B has to have the same charge as A therefore B is negatively charged.

B is repelled By C therefore meaning they both have the same charge so C has to be negatively charged.

B is attracted to D. attraction occurs between oppositely charged objects. Therefore D has to have the opposite charge of B. Since B is negative D has to be positive in order for that attraction to occur.
