Which of the following statements about Gauss's law are correct?
(There may be more than one correct choice.) Check all that apply.
If there is no charge inside of a Gaussian
surface, the electric field must be zero at points of that surface.
The electric flux passing through a Gaussian surface depends only
on the amount of charge inside that surface, not on its size or
shape. Gauss's law is valid only for symmetric charge
distributions, such as spheres and cylinders. If a Gaussian surface
is completely inside an electrostatic conductor, the electric field
must always be zero at all points on that surface. Only charge
enclosed within a Gaussian surface can produce an electric field at
points on that surface.
