Electric Charge of the Particles

This is the representation of the Coulomb force in its most general form. The charges (Q or Q’) can be two electrically charged particles. But an electrode also represents the location of a charge. The higher the two charges are, the greater their product. The force \(\overrightarrow{F}\) is a vector in the direction of the unit vector \(\overrightarrow{{r}_{0}}\) . The permittivity ε takes into account the properties of the gas between the charges.
