alleryAccording to Coulomb's law, the electrostatic force between two point charges is directly proportional to
Athe sum of the charges
Bthe difference of the charges
Cthe product of the charges
Dthe square of the distance between them
Answer & Solution
Correct answer: C. the product of the charges
Coulomb's law gives $F \propto q_1 q_2$ and $F \propto \frac{1}{r^2}$.
**Therefore, the force is directly proportional to the product of the two charges.**
