The electrostatic force ($F_{e}$) between two charges is given by the equation:

$F_{e} ext{ is directly proportional to the product of the charges and inversely proportional to the square of the distance between them}$

This can be expressed mathematically as:

F_{e} ext{ is proportional to } rac{q_1 imes q_2}{r^{2}}

This illustrates that as the distance ($r$) between the charges increases, the electrostatic force decreases.
