Coulomb’s Law Calculator

To calculate the force between two charges using Coulomb’s Law, first identify the magnitude of the charges and the distance between them. Then, apply the formula by multiplying the charges, dividing by the square of the distance, and multiplying by Coulomb’s constant (k).

The Coulomb’s Law calculator is used in physics to calculate the electric force between two or more charged particles. According to Coulomb’s Law, the force is proportional to the product of the charges and inversely proportional to the square of the distance between them.

This calculator helps with multiple scenarios, including cases involving 3 charges, 4 charges, or other configurations like squares or triangles.
