Vacuum permittivity
Isn´t there a term of 1/ε_0 missing in both equations? Neither equation will give the correct units the way they are now (C²/m iso VC=J, and C/m² iso V/m), and that is because they should be multiplied by 1/ε_0. Or is there some ε_0=1 convention going on? I don't think that is very clear here.
