Electron moving in a field. Electric dipoles. Superposition. The . total electric force . Charges are conserved. Charges are additive in nature. Charges are quantised.. PROPERTIES OF ELECTRIC CHARGES. PRODUCTION OF ELECTRIC CHARGE. We can get electric charge by three ways. By friction or rubbing. Coulomb's Law : . Coulomb's Law states that the force between two point charges Q. 1. and Q. 2. is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.. Defining the Electric Field. Michael Faraday suggested the idea of a force field to explain how the electric force can act at a distance.. An . electric field . is a property of the space around a charged object that exerts forces on other charged objects. .
