The correct equation for Coulomb's law for the interaction force F between two point electric charges $q_{1}$ and $q_{2}$ located at the distance r from each other is:<br /><br />$F=k\frac {q_{1}q_{2}}{r^{2}}$<br /><br />This equation states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The constant k is known as the Coulomb constant and has a value of approximately 8.99 x 10^9 N m^2/C^2.
