Here is a cylinder on whose surfaces there is a vertical electric field of varying magnitude as shown. The electric field is uniform on the top face, and also uniform on the bottom face.

This cylinder encloses

no net charge.

net positive charge.

net negative charge.

There is not enough information available to determine whether or not there is a net charge inside the cylinder.
