i need help doing error propagation..

the values i have are u_0=4pi*10^(-7), I=3A, R=.2m and slope=.4118 +/- .008984

the equation is:

Tnm 2.29 * 10-5p -= slope 2R (0.4118)(2)(2m)

Answer #1

\DeltaBearth,N/Bearth,N = \pm\DeltaSlope/slope

\DeltaBearth,N/(2.29 x 10-5) = \pm (0.008984/(0.4118))

\DeltaBearth,N = \pm 5 x 10-7
