Electron brought to rest by the E-field, potential difference question

[QUOTE="cookiemnstr510510, post: 6064527, member: 650627"] right, my mistake. Will edit. Im not sure slightly confused, do you mean once it stops what happens after? I think you meant while being brought to rest was it moving from a region of low electric potential energy U to a region of high electric potential energy U. The answer to this: Since it is being stopped this means it was traveling towards a negatively charged object (or group of objects). The closer you bring electrons to negatively charged things its electric potential energy increases (and its kinetic energy decreases to zero, which is why it stopped in the first place). So It was moving from a lower electric potential energy to a higher electric potential energy. Using my answer to part 1 and the equation ΔV=U/q, if U is small then ΔV is small and vice versa. Therefore the electron went from a region of lower electric potential to higher electric potential. [/QUOTE]
