    E = eV where e is electron charge is equal to 1.67 x 10^-19. and V is potential different

    i have one more...what is the force per meter of lenght on a wire carrying a .5A current due to a .5 tesla-magnetic field?

    Answer is very simple in natural units: Energy will be 100 keV

    Use \[F = BIL \] for that one, but you will solve for \[ \frac{F}{L} \] to get the force per unit length.
