Object a is negatively charged. object a and object b attract. object b and object c repel. object c and object d attract. what type of charge does object b , object c, and object d possess?

Remember opposites attract and same charges repel each other.

Object A= negatively charged.

Object A and B attract so B must be positively charged.

Object B and C repel so because B is positively charged C must also be positively charged.

Object C and D attract and because C is positively charged, D must be negatively charged.

the answer would be c. motion and direction

i hope this : )
