"Consider Gauss's law."
I suppose the setup in this particular case that is confusing me. I'm probably making it harder than what it needs to be. I instinctively want to say it's the E * the Area of the cube, but that's not right.
I have the homework problem below with which I'm totally stumped. Can anyone out there help me out?
A small cube of volume 9.0 cm^3 is 0.30 cm from a metal sphere that has charge 3.00 coulombs. If the cube is empty, what is the total flux through it?
