Three electrons and one proton are at rest, all at an approximate infinite distance away from each other. This original arrangement of the four particles is defined as having zero electrical potential energy. 1. Now, if one electron is released from the triangle, where will it arrive after it returns to zero potential energy, and what will be its final velocity? - In part (1) of the problem, the final velocity was undefined. Why is this, and what piece of information would we need to find the actual final velocity of the electron
