Understanding Inward Flux of an Object

[Ronnin]

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.

Yes, the type of material (conductor or insulator) can affect the inward flux. Conductors are better at conducting electricity, so they will have higher flux than insulators. In your example, since the block is insulating, the inward flux will be lower than if it were a conductor. To answer your question, you should post the entire homework question so we can provide a more specific answer.
