Coulomb’s law is a function developed in the 1780s by physicist Charles-Augustin de Coulomb. It explains how strong the force will be between two electrostatic charges. Electrostatic means electric charges without any motion.

Scale

---

Coulomb’s law explains the scale between two electric charges. The scale of electrostatic force follows the function below.

$$F=K_c\frac{q_1{q}_2}{r^2}$$

Coulomb’s law explains that the force scale F is relative to ratio of $q_1,q_2,\frac{1}{r^2}$.

While $K_c$ remains constant, when multiples of $q_1$ and $q_2$ become bigger, the electrostatic force will also get bigger. When the distance $r$ becomes bigger, the electrostatic force will become smaller by the ratio of $\frac{1}{r^2}$.
