1. The problem statement, all variables and given/known data When is the net flux for a cube 0 and when is it not? 2. Relevant equations ∫EdA= Q/8.85E-12 3. The attempt at a solution if you have no test charge then the flux of a cube is zero. but if you have a test charge then the net flux is the charge divided by 8.85E-12. I just want to make sure I am thinking about this correctly.
