Suppose we have a charge, q1=1 μC. This charge makes an electric field some distance r=73 cm away from it. Now suppose our measurement of q1 is only accurate to within 0.2 μC, and our measurement of r is only accurate to within 1.5 cm. What is the uncertainty in our field calculation due only to the uncertainty in the charge separation r?
