A planar slab of thickness of 5.00 cm has a uniform volume charge density of 5.20×10^-2 C/ m^3. Find the magnitude of the electric field at all points in space both inside and outside the slab, in terms of x, the distance measured from the central plane of the slab. What is the field for x = 1.25 cm? What is the field for x = 10.00 cm?
