The force of repulsion between two charges is considered as:
Correct answer: B. Positive
- A. Negative
- B. Positive
- C. May be positive or negative
- D. Cannot be determined
Explanation
According to Coulomb's law When the charges have opposite signs, the force is attractive (negative F), while if both charges have the same sign, the force is repulsive (positive F).F=k q1q2/r2

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.
