Electrostatic force via charges and distance

The Coulomb’s law states that the electrostatic force between two point charges in a vacuum is proportional to their values and inversely proportional to the square of the distance between them.

Notation:

  1. \(\varepsilon_0\) (epsilon_0) is vacuum_permittivity.

Notes:

  1. Per this law, positive force indicated that the two charges repel (both charges are of the same sign), and negative force indicates that they attract one another (the charges are oppositely charged).
