Classical electromagnetism

In electrostatics, where charges are not moving, around a distribution of point charges, the forces determined from Coulomb's law may be summed.

Divergence theorem

Two examples are Gauss' law (in electrostatics), which follows from the inverse-square Coulomb's law, and Gauss' law for gravity, which follows from the inverse-square Newton's law of universal gravitation.

Euler's three-body problem

Euler's problem also covers the case when the particle is acted upon by other inverse-square central forces, such as the electrostatic interaction described by Coulomb's law.

Hairpin ribozyme

In the laboratory, a functional interaction between the two domains is promoted by the addition of cations, whose positive charge suffices to overcome the electrostatic repulsion of the negatively charged RNA backbone.

Laplace–Runge–Lenz vector

The hydrogen atom is a Kepler problem, since it comprises two charged particles interacting by Coulomb's law of electrostatics, another inverse square central force.

Point particle

The fundamental equation of electrostatics is Coulomb's law, which describes the electric force between two point charges.
