Question: 5. A thin insulating rod with uniformly spread positive charge Q is bent into a circle of radius R. The center of the circle

5. A thin insulating rod with uniformly spread positive charge Q is bent into a circle of radius R. The center of the circle is z = 0. a. Without calculation, roughly plot the magnitude of the E field vs. z. (Hint: think about E far away, and near the center.) b. In terms of R, at what z value is the E field at its maximum value? (A: R C. Find the maximum E field value.
