Two large flat parallel sheets have opposite uniform surface charge densities ±o and are separated a distance d. A large, uncharged conducting slab of thickness d/3 is parallel to the charged sheets, centered between them. Find the electrostatic potential as a function of distance y perpendicular to the sheets. Take the reference potential V = 0 and the origin y = 0 to be at the negative sheet.
