Electric fields and mean free path?

  1. Oct 14, 2013 #1
    Just need someone to tell me if I'm doing this right.

    If I have accelerated a particle in which the mean free path is 50nm and I need the collision to be 5eV would this be correct in determining the required electric field strength?

    5/.00000005 = 100MV/m

    No. Double check your units.
