Please help me with the following question: An electron (mass m = 9.11 X 10^-31 kg) is accelerated in the uniform field E (E = 1.85 X 10^4 N/C) between two parallel charged plates. The separation of the plates is 1.20cm. The electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate. (a) With what speed does it leave the hole? (b) Show that the gravitational force can be ignored. I would also REALLY appreciate it if someone could direct me to a site that teaches this particular part of physics. I usually check things like this that I dont understand on www.physicsclassroom.com, but they dont teach this particular area.
