What is coloumbs law

Coulomb's law, or Coulomb's opposite square law, is a trial law of material science that measures the measure of power between two stationary, electrically charged particles. The electric power between charged bodies very still is customarily called electrostatic power or Coulomb power.

Coulumbs law states that the force of attraction or repulsion between two charges, Q and q is directly proportional to the charges and inversely proportional to the distance apart.
