A proton travel across two plates connected toa battery. The electron travels from a hole in the positive plate across the gap and hits the negative plate. Compared to the plate wtih a hole in it, will the proton gain or lose energy?
gain energy
lose energy.
An electon passes through a plate with hole in it as it travels across a gap and into an opposite plate. The plate with a hole in it is connected to the negative side of a battery. The opposite plate is connected to the positive side of a battery. Will the electron gain or lose energy as it travels across the plates.
gain energy
lose energy
