1. The problem statement, all variables and given/known data If we have an electric field with a positive and negative plate: The field lines will be going from the positive to the negative, so down. But, if we put an electron between these two plates, it will be attracted to the positive plates, so it will have a force vector pointing up. The electron has more potential energy at B and less at A If the electron moves from point A to point B; was this caused by the field? Will the electric field move the electron from point A to point B, even though the electron wants to attract to the positive terminal? So my basic question is: Will an electric fields force vector be DOWN for a proton and UP for an electron? Or will it always be DOWN (from positive to negative) no matter what? Thereby increasing the electrons potential energy? +++++++++++++++++++++++ A B ------------------------------ 2. Relevant equations 3. The attempt at a solution Not really sure at the attempt, because it's not really a question from my book, but more of a question from myself.
