The most important aspect of this result is that both the gravitational and electrostatic forces decrease as the square of the distance between the particles.

The magnitude of the force is linearly proportional to the net charge on each object and inversely proportional to the square of the distance between them. (Interestingly, the force does not depend on the mass of the objects.) The direction of the force vector is along the imaginary line joining the two objects and is dictated by the signs of the charges.

The wave impedance of free space (η0) is the ratio of the magnitude of the electric field intensity to that of the magnetic field intensity in free space and is √μ0/ϵ0≅376.7 Ω.

The electric field only depends on the configuration and size of the source charges. Once the electric field is found, it allows us to calculate the force on any test charge. The electric force between two point charges is described by Coulomb's Law.
