Net Flux due to charge on surface

  1. Oct 14, 2007 #1
    Hello,
    Will a point charge directly on the surface affect the net flux through the surface?

    (will it contribute to the next flux like a point inside the surface? i thought about it, and it seems like it will produce the same # of electric field lines going in as going out, so would it behave like a point charge outside the surface?)

    I'd say that Gauss's law refers to the charge within a closed surface; if a point charge were on the surface, its field would be undefined at that point.

    hmm... i never knew that could happend, i thought it would either contribute to the flux or has nothing to do with it.
    thanks!
