If point P is located outside the charge … WebWith a point charge, the appropriate Gaussian surface was a sphere. In this case, let's work with a cylinder. A surface in the form of a box would work, too, but it's got six sides while a cylinder only has three, which simplifies matters a little. A diagram of the plate, with the Gaussian surface passing through the plate, is shown here:
