never mind, I got it. thanks!

Ok... So 1eV = 1.6*10^-19J 750eV*1.6*10^-19 = 1.2*10^-16 = j v = sqrt(2j/m) = sqrt(2.4*10^-16 / 9.11*10^-31) = 1.623*10^7 still not right, is it?

I found an old post with an almost identical question: https://www.physicsforums.com/showthread.php?t=54092 However, I still don't see how to work the problem. My question is phrased exactly the same, except B = 0.0170T and it's a 750eV electron. I have absolutely no clue how I'm supposed to...

A continuous line of charge lies along the x axis, extending from -x_{0}{ to -\infty. The line carries a uniform linear charge density \lambda_{0}. What is E, the magnitude of the electric field, at the origin? Use the symbols \lambda_{0}, x_{0} and k (for the Coulomb constant) to enter your...

First I want to say thanks in advance - I found this site through Google and am thrilled! All I have left to graduate is Physics II (Electromagnetism & Waves), so I'll finally be walking on August 5. IF I can pass this class, that is. I'm a non-traditional student, and it's been about 10...
