That is, until a very bright scientist by the name of Charles Coulomb conducted several experiments that led him to propose what is now known as Coulomb's law. This problem emphasizes the fact that even if we have two different charges, mutual electrostatic force between them will be same. An unknown amount of charge would distribute evenly between spheres A and B, which would then repel each other, because like charges repel. Ask an Expert. Most of the published literature regarding bearing capacity are often focused on linear and associative soils. The attractive force between a plane charge (in the form of a triboelectrically charged Teon plate) and an uncharged conducting sphere is investigated.
