Here is a cylinder on whose surfaces there is an electric field whose direction is vertically upward, but whose magnitude varies as shown. The cylinder encloses: no net charge. net negative charge. net positive charge. There is not enough information available to determine whether or not there is net charge inside the cylinder.
