1. The problem statement, all variables and given/known data A point charge q = 112 x 10^-9 C is placed at the centre of a cube of side l = 0.2 m. If the charge is moved all the way to one vertex of the cube, determine the flux through each of the faces. 2. Relevant equations None. 3. The attempt at a solution I looked at the answer: Flux through each face = Total flux / 24 = 2 109.23 / 24 = 527 Nm^2/C And dont understand why the 24 is used. I read somewhere that it said that the flux through the faces adjacent to the vertex where the charge is placed = 0, but I dont understand why? I think this might be why I dont understand the use of the "24". Could someone please help?
