Question
For a charged solid metal sphere with total charge Q and radius R centered on the origin: Select "True" or "False" for each statement.
1. The electric field for the metal sphere at r << R will be the same as the field of a point charge, Q, at the origin.
2. If the solid sphere is an insulator (instead of metal) with net charge Q, the electric field for r >> R would be the same as that of a conductor with the same shape and charge.
3. The net charge on the inside of the solid metal sphere is neutral.
4. The electric field near the metal surface on the outside is perpendicular to the surface.
5. The electric field anywhere inside the solid metal sphere is zero.
6. If the solid sphere is an insulator (instead of metal) with net charge Q, the net charge on the inside of the solid sphere is neutral.
