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.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 negative.
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 electric field inside the solid metal sphere is never zero.
4. The electric field near the metal surface on the outside is perpendicular to the surface.
5. 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.
6. The net charge on the inside of the solid metal sphere is neutral.
Gauss's Law: Qinside/ esub0
The Attempt at a Solution
1. False I'm not quite sure on this one
2. True I'm not quite sure on this one
3. False I;m not quite sue on this one
4. False, On the inside of a sphere the electric field is prependicular to the surface, but on the outside it wouldn't be
5. False I'm not quite sure on this one
6. True This is true becasue the net charge would be zero if the the eletric field is perpendicular.
