Extracted text: 4. A thin non-conducting rod of finite length I carries a total charge q, spread uniformly along it. Show that the magnitude of the electric field E at a distance y on the perpendicular bisector is given by E = q/[2nEo y (P + 4v?)12]. Show that, as l gets very long, the result approaches that of an infinite line charge with charge/unit length 2.
