Find the speed of the electron when it exits the hole

Reference no: EM13293761

An old-style TV set places 50 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.

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

B) What is the speed of the electron when it exits the hole in the plate?
