Coulomb’s law formula calculator is a useful online conversion tool to calculate either force, charge, or distance between of point charges provided that one of the four parameters (either force, charge on first charge, charge on second charge, or distance between charges) is known.
Coulomb’s Law Formulas
Where
F = Force between two charges also known as the Coulomb force
q1 and q2 = magnitudes of two charges
r = Distance between two charges
k = Constant of proportionality – In calculator it is considered: 8.99 * 1e9
