Find the electric field a distance $z$ above the center of a square loop (side $a$ ) carrying uniform line charge $\lambda$ (Fig. 2.8 ). [Hint: Use the result of Ex. 2.1.]
(II) Use your result from Problem 46 to find the electric field (magnitude and direction) a distance $z$ above the center of a square loop of wire, each of whose sides has length $\ell$ and uniform charge per length $\lambda$ (Fig. $63 ) .$
