1. If an alpha particle (q=+2e, m = 6.64*10^-27kg) is released from the positive plate (Vab=120V and the distance separating the plates is 12cm), with what velocity will it hit the negative plate?
2. An electron is fired from a negative plate toward a hole in a positive plate. It then passes between two parallel plates that are 3cm long and 2cm apart with a voltage of 550Volts across them. If the accelerating voltage across the two original plates is 900 volts what is the final velocity of the eletron?
Ooooh my head spins. I haven't the slightest clue where to start. Could someone give me a hint?
