I'm a bit confused on an issue, does whether an object is a conductor or insulator affect the inward flux in any way if the object contains a charge? The reason I ask is on one of my homework questions it states that a insulating block of dimentions 3x2x1m contains a charge of -24nC. Then it asks to find the flux on one side that is 6m. The solution shows basically q/Enot/6, but how can this be? Because of the shape of the block, flux is not going to be uniform for each side. Is my thinking correct, or should I just post the entire question.
