The Electrostatic Potential Energy calculator computes the magnitude of potential energy between two charged particles based on their charge and the distance between them.
INSTRUCTIONS: Choose units and enter the following:
Electrostatic Potential Energy (Eel): The results are returns in electron volts (eV). However, this can be automatically converted to compatible units via the pull-down menu.
The Electrostatic Potential Energy equation computes the magnitude of the potential energy resulting from the electrostatic interaction of two charged particles having charges of `Q_1` and `Q_2` respectively, where the particle are separated by distance d.
The potential energy is proportional to the product of the two charges and inversely proportional to the distance between the charges, so `E_"el" prop (Q_1*Q_2)/d`.
The constant of proportionality in this equation is the Coulomb Constant, `k_e`.
The potential energy can be a due to either the force of attraction (between particles of opposite charge) or the force of repulsion (between particles of the same charge).
