Imagine a proton at rest a certain distance from a negatively charged plate. After being released it collides by the plate. Then imagine an electron at rest the same distance from a positively charged plate. Suppose that the amount of net charge of the plates is the same in both cases. In which case will the moving particle have the greater speed when the collision occurs?
1) They will have the same speeds.
2) The proton will have the greater speed.
3) The electron will have the greater speed.
4) It cannot be determined.
