As already mentioned above, the electric force between two particles decreases with the inverse square of the distance, just as does the gravitational force. Coulomb, who investigated the repulsion between small balls charged by rubbing, discovered the dependence of the electric force on distance through experiments. His experimental results are summarized in coulomb’s Law – … Read more
