Coulomb's Law - Mathematical Form

For two point...

Question

For two point charges $q_{1}$ and $q_{2}$ , $q_{1} q_{2} < 0$ . What is the nature of electrostatic force between two charges?

Open in App

Solution

If $q_{1} q_{2} < 0$ , then either of $q_{1}$ or $q_{2}$ is positively charged and the other is negatively charged and there is the force of attraction between them.
