Which of the following is a correct statement of Gauss's Law? The net electric flux through a closed surface is zero only if the surface contains no charges of any kind. The net electric flux through a closed surface is proportional to the net electric charge enclosed by that surface. The net electric flux through a closed surface is only zero if the field evaluated on the surface is zero. The electric field everywhere on a surface is equal to the charge enclosed by the surface.
Which is true?
Electric flux through a surface is maximized if the field lines and the area vector of the surface are perpendicular. Electric flux through a surface depends only on the area of the surface, and not on the field strength. Electric flux through a surface is maximized if the field lines and the area vector of the surface are parallel. Electric flux through a surface depends on how much charge is distributed over the surface.
Consider a conductor with net positive charge. Which is true?
The net charge is distributed over the outer surface of the conductor.
There is no general way that the net charge is distributed; it's different for every conductor.
The net charge is distributed throughout the volume of the conductor.
The net charge is distributed over the outer surface of the conductor, unless there's a cavity; in that case, it's distributed over the inner surface, too.
Typeset Gauss's Law mathematically in its surface integral formulation, relating the closed-surface integral of the electric field to the net charge enclosed by the surface.
