Coulomb's law is defined by the following formula
\(\displaystyle F= k_e \frac{q_1 · q_2}{r^2}\)
\(F\) = electrostatic force in newtons
\(k_e\) = Coulomb constant: 8.987.551.787,3681764 Nm2 C-2 ≈ 8.988·109 Nm2 C-2
\(q_1\) = Charge of the 1st object in coulombs
\(q_2\) = Charge of the 2nd object in coulombs
\(r\) = distance between the objects in meters
