# An infinite nonconducting slab of thickness 2d is oriented parallel to the yz-plane and centered at the origin, occupying the region -d \le x \le d. The slab carries a uniform positive volume charge density \rho_0. Which of the following graphs best represents the electric field component E_x as a function of position x along the x-axis?

An infinite nonconducting slab of thickness 2d is oriented parallel to the yz-plane and centered at the origin, occupying the region -d \le x \le d. The slab carries a uniform positive volume charge density \rho_0. Which of the following graphs best represents the electric field component E_x as a function of position x along the x-axis?

![A perspective view of a thick vertical rectangular slab centered at the origin of a horizontal coordinate axis labeled x. The slab extends vertically and into the page, bounded by two parallel vertical planes perpendicular to the x-axis at x = -d and x = +d. The interior region between x = -d and x = +d has light gray shading and contains three small plus signs indicating positive volume charge density \rho_0. The horizontal x-axis passes perpendicularly through the center plane of the slab at x = 0, with an arrowhead pointing to the right labeled x. Two tick marks on the x-axis mark -d and +d, with 0 at the center. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-slab-diagram-1790604538-VJBIEj.jpg)
