Force between charges formula
WebMar 20, 2024 · The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the … WebCoulomb's Law gives the electric force between two point charges. This force obeys an inverse square law, meaning that if distance is doubled, the force is one quarter what it was. Coulomb's law, named after a physicist, is important in understanding one of the most fundamental forces of nature.
