I just have a quick question, could anyone clear up how the unit for Electric Field is Derived? From what i Know its either V/m or N/C.. but how does it get there from E=f/q?
i found a derivation of this online and basically you have to break down the units and work the equation out:
the units of these are as follows:
k ----- Nm^2/C^2
q ----- C
R^2 ----- m^2
so that would be E = [ (Nm^2/C^2) (C) ] / (m^2)
if you simplify you will get N/C
