Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest. This electric force is conventionally called the electrostatic force or Coulomb force. [2]
The mathematical formula for the electrostatic force is called Coulomb’s law after the French physicist Charles Coulomb (1736–1806), who performed experiments and first proposed a formula to calculate it.
This equation is known as Coulomb’s law, and it describes the electrostatic force between charged objects. The constant of proportionality k is called Coulomb’s constant . In SI units, the constant k has the value k = 8.99 × 10 9 N ⋅ m 2 /C 2. k = 8.99 × 10 9 N ⋅ m 2 /C 2.

Coulomb's Law. The force between two charged objects is directly proportional to the magnitude of each charge and inversely proportional to the square of their separation.
The magnitude of the electric force (or Coulomb force) between two electrically charged particles is equal to \[\left|\mathbf{F}_{12}\right|=\frac{1}{4 \pi \varepsilon_{0}} \frac{\left|q_{1} q_{2}\right|}{r_{12}^{2}} \label{Coulomb}\]
27 maj 2024 · At its core, Coulomb’s Law states that the magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
