Neutral bodies are considered as composed of equal numbers of positive and negative electric charges whose fields exist in space but cancel out exactly everywhere except at the location of charges. Mass and Newton?s law of gravitation are expressed in terms of the number of electric charges constituting two separate bodies in space. It is proposed that an electric field from one charge in a body exerts a force to cause a small strain on a charge encountered in another body, such that force of repulsion is slightly reduced and force of attraction similarly increased. The result is force of attraction in accordance with Coulomb?s and Newton?s inverse square law. The assumption here is based on the fact any force acting on a body causes a strain, no matter how small.
