If more field lines leave a closed surface than enter that surface, then O an error has been made since the number of field lines entering a surface must equal those leaving the surface. a net positive charge is contained inside the surface. a net negative charge is contained inside the surface. an operating electron gun is inside the surface. there must be a charge on the surface.
