Calculating % Error in Magnetic Field

[qswdefrg]

Homework Statement

Hello. One section of my lab requires me to calculate the percentage error in the magnetic field at the closest separation.

My data for that point in time are as follows:

x₁=0.6 cm \pm 0.1 cm
v₁=0.006 m/0.02 s = 0.3 m/s

Homework Equations

where delta x, y, z are the errors in measurement
and x, y, z are the actual measurements

The Attempt at a Solution

Would I be correct in assuming that my time, 0.02 s, has an error of zero? Then

delta z = 0.3 (0.001/0.006)
delta z = 0.05

so v₁= 0.3 m/s \pm 0.05 ?

The percentage error of the magnetic field can be calculated by:percentage error = (delta x / x1) * 100percentage error = (0.1 / 0.6) * 100percentage error = 16.67%
