Object A is negatively charged. Object A and Object B
repel. Object B and Object C attract. Object C and Object
D repel. What type of charge does Object B, Object C, and
Object D possess?

B=Negative C=Positive D=Positive

Explanation:objects that repel each other means they have the same polarity. objects that attract have the opposite polarity A is negatively charged if A and B repel then A and B are both negative. B is negatively charged if B and C attract then they have reverse polarity which makes C positively charged. C is positive if C and D repel then that means that C and D have the same polarity making D positively charged.
