An old-style TV set places 25 kV across two plates of a parallel plate capacitor. An electron is released very close to one plate, and it accelerates rapidly towards the second plate which has a hole drilled through it. The electron exits the hole and hits a phosphor on the glass screen where the picture appears and the phosphor glows.

1. If the plate where the electron is released is 0 V, what is the voltage of the plate with the hole in it?

2. What is the speed of the electron when it exits the hole in the plate?
