A very long uniform line of charge with charge per unit length λ = +5.00 μC/m lies along the x-axis, with its midpoint at the origin. A very large uniform sheet of charge is parallel to the xy-plane; the center of the sheet is at z = +0.600 m. The sheet has charge per unit area σ = +8.00 μC/m2, and the center of the sheet is at x=0, y=0. Point A is on the z-axis at z = +0.300 m, and point B is on the z-axis at z = -0.200 m.
