These two equations concern a lab on the measurement of E/M by the Brainbridge Method.

Question

I need to derive the absolute error for two different equations,
the first one is: e/m = 2V/B2R2
treat (e/m) as a SINGLE VARIABLE when doing the derivation.

The second is B=8μ0N(I-Io) / √125a
whre μo=4π*10-7 T*m/A
Io=zero referenc current

You may want to EXPLICITLY substitute in a new variable, (Inet), in place of (I – Io) [ie, let Inet = I – Io]
