As per Coulomb's law, the force of attraction or repulsion between two-point charges is directly proportional to the:
Correct answer: C. Product of the magnitude of charges
- A. Sum of the magnitude of charges
- B. Square of the distance between them
- C. Product of the magnitude of charges
- D. Cube of the distance
Explanation
Option C is correct. Coulomb's law states that the force is directly proportional to the product of the magnitude of charges (q1 * q2).

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.
