1. The problem statement, all variables and given/known data A point charge q is placed at one corner of a cube of edge a. What is the flux through each of the cube faces? 2. Relevant equations 3. The attempt at a solution I drew a diagram of the situation. I'm pretty sure that I should use Gauss' Law and some symmetry arguments but I am not sure how to integrate over the cubes faces taking into account that the electric field produced by the point charge is radially outwards, like a sphere cutting through the face of the cube ( poorly described I know, sorry). Thanks for the help.
