The figure shows two very large slabs of metal that are parallel and distance apart. Each slab has a total surface area (top + bottom) .

The figure shows two very large slabs of metal that are parallel and distance apart. Each slab has a total surface area (top + bottom) . The thickness of each slab is so small in comparison to its lateral dimensions that the surface area around the sides is negligible. Metal has total charge and metal has total charge . Assume is positive.
