Question

The electrostatic force between two point charges is directly proportional to the

• A. Sum of the charges
• B. Distance between the charges
• C. Permittivity of the medium
• D. Square of the distance between the charges
• E. Product of the charges

Answer 1

Answer: (E)

Product of the charges

By Coulomb's law
$F=\frac{1}{4\pi {\epsilon }_0}\cdot \frac{q_1{q}_2}{r^2}$
So, the electrostatic force between two point charges is directly proportional to the product of the charge.
