Homework Help: Electric Potential

  1. Oct 4, 2009 #1
    I'm not asking anyone to solve my homework for me but I am stuck on this problem.

    The problem includes finding the time is takes for an electron with a horizontal initial speed v m/s to make it through a region with an electric field X V/m pointing vertically upward.

    One equation I found that could be useful is E = - [tex]\Delta[/tex]V/[tex]\Delta[/tex]s . This includes the electric field and the distance that the electron travels in the problem but does not include velocity or distance. I have been searching for some link in equations or way to substitute but I am honestly stuck. Any help would be appreciated!!

    Take a look at the Lorentz Force.
