Asked by Molly
Two identical metal plates with small holes are aligned a distance L=6.7 cm apart. They have a potential difference of 131 Volts. An electron can enter through the hole in the negative plate and exit through the hole in the positive plate. If it enters with a velocity of 3290 km/s at the negative plate, with what velocity does it exit at the positive plate?

It gains KEnergy = Vq. add that to the initial KE, and solve for velocity.
