given: a cube of sides 's' and a point charge 'q' . q is located a very small distance, on the extension of one diagonal of the cube, from this particular corner of the cube. what is the electric flux through the sides of the cube that meet at this corner.
answer: q/24E
my question: what is the process of coming by this answer? :confused:

Well Gauss' Law states that: E.F. = q/E, so the question is where does that darn 1/24 come from?
I'm trying to interpret the question correctly. Are the sides referring to the two planes that intersect to make one of the outer points, or something else?

How I'd do it is to draw a square on paper (I'm slow in the head) and position your source just 'delta' off a corner. Integrate quarter circle slices. Serve with ice cream.
