A flat circular loop of with radius R lies in the xy-plane centered at the origin. Its linear charge density is 2 = A cos p. What is the total charge on the loop? b. Calculate the electric field in a point on the z-axis, a distance d above the origin. Find the limit of the electric field as z gets very large compared to R (not infinitely large, E does not become zero). 2. C.
