Question

According to Coulomb's law, the electrostatic force between two charges is ________.

• A. directly proportional to the cube of the distance between charges
• B. inversely proportional to the product of the charges
• C. inversely proportional to the square of the distance between the charges
• D. None of the above

Answer 1

The correct option is C inversely proportional to the square of the distance between the charges

Electrostatic force between the charges $F=\frac{k{q}_1{q}_2}{d^2}$
where $d$ is the distance between two charges.
Thus option C is correct.
