Two very large charged parallel metal plates are 13cm apart and produce a uniform electric field of 2.76×10^6 N/Cbetween them. A proton is fired perpendicular to these plates, starting at the middle of the negative plate and going toward the positive plate.
Part A How much work has the electric field done on this proton by the time it reaches the positive plate?
