## shortcake1970 Group Title how much energy would an electron acquire if it moved through a potential difference of 100kV? one year ago one year ago

1. gerryliyana Group Title

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.
