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..
