Electric flux

  1. Apr 16, 2009 #1
    If there's a point charge at the origin, I want to find two closed surfaces such that the flux through one of them is zero while the other is not.

    I know this may seem trivial but I just want to make sure I understand the question.

    My answer would be that to get a zero flux, the closed surface must NOT enclose the charge at the origin while for the non-zero flux, the surface must enclose the charge; is this OK?
