A three-dimensional schematic showing an infinite non-conducting slab centered on the xy-plane. The slab has a uniform thickness 2d along the z-axis, extending from z = -d to z = +d. A vertical z-axis line passes through the center of the slab, with tick marks at z = d, z = 0, and z = -d. Inside the slab, a shaded cylindrical Gaussian surface of cross-sectional area A and height 2z is centered at z = 0, extending symmetrically to +z and -z where z < d. Two vertical vectors pointing outward from the top and bottom circular end-caps of the cylinder are labeled \vec{E}. A label \rho_0 is placed inside the slab region. No other labels, lines, text, or axes appear.
Non-conducting slab of thickness 2d with uniform volume charge density \(\rho_0\).
An infinite non-conducting slab parallel to the x y-plane has a uniform thickness 2 d, extending from z = -d to z = +d, and carries a uniform volume charge density \(\rho_0\). Which of the following expressions gives the magnitude of the electric field \(E(z)\) inside the slab at a position \(z\), where \(0 \le z < d\)?
