Three objects are brought close to each other, two at a time. When objects A and B are brought together, they repel. When objects B and C are brought together, they also repel. Which of the following is true?
Correct answer: C. All three objects possess charges of the same sign.
- A. Objects A and C possess charges of the same sign, but not B.
- B. Objects A and C possess charges of the opposite sign.
- C. All three objects possess charges of the same sign.
- D. One object is neutral.
Explanation
Like charges repel each other by nature and unlike charges attract each other by nature. Since all of them repel; all of them must be of the same sign. As explained above both options A and B are correct So, D is incorrect.

About Electrostatics
Electrostatics describes forces between charges through Coulomb's law, electric fields and field intensity, then uses electric potential to measure energy per unit charge. Capacitors store charge and electrical energy, with capacitance depending on geometry and dielectric material, not simply on the amount of charge present.
