1. The problem statement, all variables and given/known data Note this is a PRACTICE midterm problem. Not due for homework or for a grade. My exam is on Tuesday "an electron moves from point A to point B in a uniform electric field as show below. Rank the electrons in diagrams 1 through 2 by the changes in potential from greatest to least when traveling from A to B" I can't attach an image but it's VERY straight forward. Answer A Answer B --------------------> (Direction of E field) --------------->(Direction of Efield) Point A Point B Point B Point A The distances are the same. Just swapped. 2. Relevant equations V = U/q 3. The attempt at a solution My reasoning was (A then B) because in the first diagram, we must do work against the electric field, increasing the potential energy of the electron, therefor increasing the electric potential. The converse is true for part B, we move in the direction of the force and so the potential energy of the electron decreases, and so should the electric potential. I am messing up the concept somewhere along the road because the answer is actually B then A.
