1. A flat metal plate has a uniform surface charge density of 3E-9 C/m^2. A second flat metal plate, parallel to the first, has an equal and opposite surface charge density. The two are close enough together that they can be modeled as infinite planes. How much pressure (force per square meter of surface) is required to pull them apart? How much work (per square meter of surface) is required to separate the plates by a distance of 1 cm? It とと
