Work done on a charge by an electric field

  1. Jan 31, 2010 #1
    1. The problem statement, all variables and given/known data

    Find the work done a charge "q" of mass "m" by an electric field of magnitude "E" when it's moved a distance "d"



    2. The attempt at a solution

    [tex]W = \int_A^B F_e \cdot dr = F_e \int_A^B dr = F_e d = qEd[/tex]

    I used the Lorentz force equation for electrostatics at the end. I'm not sure if I did it correctly. I never used the mass given but I'm pretty sure I don't need it.
