# A nonconducting slab of infinite extent in the \(y\)- and \(z\)-directions has a uniform positive volume charge density \(\rho_0\) and occupies the region \(-d \le x \le d\), as shown in the figure. Which of the following graphs best represents the \(x\)-component of the electric field, \(E_x\), as a function of position \(x\)?

![A cross-sectional view of an infinitely wide slab centered at x = 0 in a Cartesian coordinate system. The slab is bounded by vertical dashed lines at x = -d and x = d, shaded light gray with positive charge symbols (+) distributed uniformly throughout its interior. The horizontal x-axis extends through the center of the slab, with tick marks labeled -d, 0, and d. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1785830578-HkKnmh.jpg)
