Question:

An infinite plane slab, of thickness 2d, cames a uniform volume charge density p (Fig. 2.27). Find the electric field, as a function of y, where y = 0 at the center. Plot E versus y, calling E positive when it points in the + y direction and negative when it points in the ? y direction.?
