Electron between 2 non-equally+oppositely charged parallel plates
If there are two parallel plates of opposite charge, an electron will experience a resultant force and accelerate towards the positive plate. What would happen if there was a positive plate of one positive voltage and the other with a greater positive voltage? Would the electron travel away from the lower voltage to the higher voltage or would distance depend on it? Would there be two opposing attractive forces? If there are two parallel plates where one is neutral and the other is positively charged would it behave the same way? Thanks

If these are ideal infinite plates, then the electron will go to the plate with greater positive charge. The net force would point that way. Same if one is neutral and the other is positive. It doesn’t depend on distance from the plates. This is because the force from an infinite charged plate is constant.
If the plates are not ideal or infinite, then it’s more complicated and depends on distance from the plates, because the forces are more complicated.
alright, thanks!
