Net Flux due to charge on surface

Click For Summary
SUMMARY

A point charge located directly on the surface of a closed surface does not contribute to the net electric flux through that surface. According to Gauss's Law, only charges enclosed within the surface affect the net flux. A charge on the surface results in an equal number of electric field lines entering and exiting the surface, leading to a net flux of zero. This understanding clarifies the behavior of electric fields in relation to surface charges.

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 happened, i thought it would either contribute to the flux or has nothing to do with it.
thanks!
