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.
