A negative charge − Q is placed inside the cavity of a hollow metal solid. The outside of the solid is grounded by connecting a conducting wire between it and the earth. Is any excess charge induced on the inner surface of the metal? Is there any excess charge on the outside surface of the metal? Why or why not? Would someone outside the solid measure an electric field due to the charge − Q ? Is it reasonable to say that the grounded conductor has shielded the region outside the conductor from the effects of the charge − Q ? In principle, could the same thing be done for gravity? Why or why not?
