A proton moves parallel to an electric field between points A and B. The change in the proton's electric potential energy is EPEB – EPEA. If the proton is removed from point B and replaced with an electron, how does the change in electric potential energy of the electron compare to the change in electric potential energy of the proton as the electron moves from point B to point A?
The change in electric potential energy for the electron is EPEA – EPEB.
The change in electric potential energy for the electron is EPEB – EPEA.
The change in electric potential energy for the electron is EPEB + EPEA.
The change in electric potential energy for the electron is zero joules.
