This calculator is used to calculate the electric potential energy between two point charges. Electric potential energy is the energy that two charges have due to their position in an electric field.

To use the calculator, enter the values for the two charges and the distance between them in meters. Then click the "Calculate" button. The result will be displayed in Joules.

The formula used for the calculation is U = k * (q1 * q2) / r, where k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.
