If yes, state roughly where this point will be. Q221) If the electric flux through a closed surface is zero, is the electric field necessarily zero at all points on the surface? What about the converse: If E = 0 at all points on the surface, is the flux through the surface zero? Q225) The electric field E is zero at all points on a closed surface; is there necessarily no net charge within the surface? If a surface encloses zero net charge, is the electric field necessarily zero at all points on the surface? Q2212) A conductor carries a net positive charge Q. There is a hollow cavity within the conductor, at whose center is a negative point charge q (Fig. 2223). What is the conductor, at whose center is a negative point charge q (Fig....
