Electrostatic force or Coulomb's law

`F = k*(q_1*q_2)/d^2`
Calculator of the electrostatic force between two charged bodies.
Enter 'x' in the field to be calculated.

This tool calculates the electrostatic force, called Coulomb force, between two electric charged objects according to Coulomb's law.

`F = k*(q_1*q_2)/d^2`

`F` : electrostatic force between the two objects 1 and 2 in newton (N)
k : Coulomb constant `k \approx 8.987551787368176*10^9 N.m^2.C^(−2)`
q1 : Charge of object 1 in coulomb (C)
q2 : Charge of object 2 in coulomb (C)
d : distance between the two objects in meter (m)
