Answer 2

Coulomb's law states that, "The force of attraction or repulsion between two point electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them."

\[Force = k \times \frac{ q_{1} q_{2} }{ r^{2} }\]where k is Coulomb's Constant.
