My problem is this,(adsbygoogle = window.adsbygoogle || []).push({});

Find the electrix flux through the top side of a cube. The cube's corner is on the origin, and is 'a' units on length. The charge 'q' is located at the origin, with the corner of the cube.

I am thinking I need a double integral. One to swipe the box in the y direction (theta), and one to swipe in the x direction (phi).

So, I know the component of the electric field perpendicular to the surface is (k*q*cos(theta))/(a*cos*theta)^2 . So I think I need to integrate this from 0 to (pi/4), then integrate again.

But how to set up the second integral is where I am confused...

Or maybe Im off track all together! Thx for any help
