$ F= k_e \frac{q_1 q_2}{r^2}$

Coulomb's law

Intuitive

Concrete

Coulomb's law is the static limit of the inhomogenous Maxwell equations.

Abstract

The motto in this section is: the higher the level of abstraction, the better.

Definitions

  • $F$ is the force between the two charged objects.
  • $k_e$ is Coulomb's contant.
  • $q_1$ and $q_2$ are the charges of the two objects in questions.
  • $r$ is the distance between the two charged objects.
