In general I just wanted to see if I was setting this problem up correctly. We have a cube centered around the origin and a point charge at the origin. The task is to find the flux & confirm Gauss' Law. We are however to complete the integral ourselves. So imagining the top of the cube q/(4*Pi*[itex]\epsilon)[/itex][itex]\int[/itex][itex]\int[/itex]z/(x^2+y^2+z^2)^(3/2)dxdy Would this be the correct setup or am I mucking something up?
