A glass rod is given positive charge by rubbing it against silk. The glass rod is then rubbed against a metal slab (on an insulating stand), transferring the positive charge on the rod to the slab. Which of the following statements is true concerning the electric field at a point just outside the upper surface of the slab? It is zero because the electric field is always zero for isolated conductors. It is parallel to the surface. It is perpendicular to the surface. It can have nonzero components perpendicular to and parallel to the surface of the conductor. None of these
