Consider a positively charged infinite slab with uniform volume charge density ρ1 and thickness 4a . This slab is oriented such that the two faces of the slab are located on the planes x = −2a and x = 2a , respectively. A positively charged solid sphere of radius R = 2a and uniform volume charge density ρ2 has its center located at the point on the x -axis at x = +6a , as shown in the figure below. Let ˆ i be the unit vector pointing towards the right
