Electron Deflected by Capacitor
Electron Fired by Capacitor
In this problem you must determine the time it takes an electron to reach a phosphorescent screen, the speed it will have when it reaches that screen and the amount of vertical deflection it will experience. The electron will be fired by a capacitor that has a small hole in the positive plate. It will then pass through a second capacitor that will deflect the electron vertically.

You will also be told the potential difference between the plates of the capacitors and the distance between the plates of the capacitors. You can ignore edge effects of the capacitors.
