Electrons in a cathode ray tube

[QUOTE="ZapperZ, post: 6045768, member: 6230"] This is confusing, and you're working too hard! If an electron is accelerated by a potential of 1000V, it will gain a kinetic energy of 1000 eV! So this is equal to ½mv[SUP]2[/SUP]! Use the charge of an electron "e", multiply that by 1000V and you have the kinetic energy in Joules. It should be trivial for you to find the velocity of each electron hitting the anode by then. Zz. [/QUOTE]
