The Coulomb’s Law Calculator calculates the electrostatic force between two charged particles based on their charges and the distance separating them. According to Coulomb’s law, the magnitude of this force is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them, expressed as F=k∣q1q2∣r2F = k \frac{|q₁q₂|}{r²}F=kr2∣q1​q2​∣​, where kkk is Coulomb’s constant. This calculator provides quick and precise results in newtons, helping students and engineers understand electric interactions between charged bodies in physics, electrostatics, and electrical engineering applications.
