Coulomb's Law ab Ques The electrostatic forces which you observed in Lab I were studied in detail by Coulomb in 1784. Do you think that the magnitude of the force on the larger charge is bigger than that on the smaller charge? Explain. The value of the electric field has dimensions of force, per unit charge and in SI system the units are newtons per coulomb. 2. The Coulomb's law describes the interaction between point charges. Table 1: The value of the charge on an electron is 1 x 10 Provide your answers using Blackboard. In Coulomb's Law, the force can either be repulsive or attractive due to the dual nature of charges, whereas gravitational forces are always attractive.
