Answer: Object B is positively charged and Object C is negatively charged.
Explanation: According to Coulomb's Law, like charges repel and unlike charges attract each other.
This means that positive charge will repel positive charge and will attract negative charge.
We are given three objects , in which object A is positively charged which repels object B and attracts object C.
From the above information, we say that Object B has positive charge on it and Object C has negative charge on it.
