[SOLVED] Electro Box 1. The problem statement, all variables and given/known data: A cubic box of side a = .290 m is placed so that its edges are parallel to the coordinate axes. There is NO net electric charge inside the box, but the space in and around the box is filled with a nonuniform electric field of the following form: E(x,y,z) = Kz j +Ky k, where K=4.10 N/(C*m) is a constant. 2. Relevant equations: [tex]\oint[/tex][tex]E[/tex][tex]\bullet[/tex][tex]dA[/tex] = Q/E_naught 3. The attempt at a solution I'm just inquiring as to where to begin this problem. I've only taken through a high school equivalent of first semester calculus, so I have no idea how this equation works. If anyone could point me in the right direction, I'd be very greatful!
