Represent the surface distribution of charge for a square metal plate by using dashes in such a way that the greater the surface density of charge, the farther away are the dashes from the plate.

Answer:

                The distribution of surface charge density on a square metal plate is as shown in Fig. As the surface charge density is proportional to the curvature and curvature is maximum at the corners and zero at plane surface, so dashes are equidistant from the straight portion and far-away from the corners.
