user: I'm engaged in a study on electrostatic interactions and need to analyze the electrostatic potential energy for a proton with a charge of 1.6 x 10^-19 Coulombs in a 500 Volt field, an electron with a charge of -1.6 x 10^-19 Coulombs in a 1000 Volt field, and a neutron, which has no charge, in a 2000 Volt field. Can we run these calculations?
