May 30, 2017 · The SI unit Coulomb, which is used to measure electric charges, is named after the physicist Charles-Augustin de Coulomb who introduced Coulomb’s law. Coulomb’s law states that when two charges q 1 and q 2 are placed r distance apart, a force acts on each charge according to:
Coulomb’s Law . The electrical charge of the body or particles is expressed through interaction with other charged bodies. It is known that electric forces are attractive or reflective among electrified bodies, depending on the type of elecricity.
