We have a charge, q1=4 C. This charge makes an electric field some distance r=61 cm away from it. Suppose our measurement of q1 is only accurate to within 01 C and our measurement of r is only accurate to within 15 cm.

If we were to calculate the electric field made by that charge at the indicated distance, what would be the uncertainty in our calculation due only to the uncertainty in the size of q1?

What is the uncertainty in our field calculation due to the only uncertainty in the charge separation r?

What is the total uncertainty in our electric field calculation due to the uncertainty in the size of q1 and the uncertainty in the charge separation r?
