hello everybody,
this is a question that has been buffeling me for a while. everything is in this image: http://img398.imageshack.us/img398/5213/58136160lu9.jpg
i know 2 things:
1. the total (vector) flux is 0 (no charge inside the cube)
2. the flux through each side is [tex]\int_{S}*E dA[/tex]
so I've tried
(the flux through shaded) = - (all the rest)
and calculating each side separately but i just don't get it right!
iv'e been integrating since yesterday morning and i have no confidence in my integrals anymore... :-(
could someone explain what I'm missing please?
Thanks!
