1. The problem statement, all variables and given/known data "The plate separation of a charged capacitor is 0.0800 m. A proton and an electron are released from rest at the midpoint between the plates. Ignore the attraction between the two particles, and determine how far the proton has traveled by the time the electron strikes the positive plate." 2. Relevant equations Not 100% sure. 3. The attempt at a solution I've tried using energy conservation and Newton's Second Law and I've tried to have a look at every other equation I've been given and their derivations. I'm just stuck. I think there might be a conceptual part I'm missing? If anyone could just give some hints, I'd be very grateful.
