Coulomb's law electrostatic force calculator and formulas
This function calculates the electrostatic force of the electric charge according to Coulomb's law
To calculate, enter the charge values in coulombs and the distance in meters. Then click on the 'Calculate' button.

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 Nm^{2} C^{2} ≈ 8.988·10^{9} Nm^{2} 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
