Okay, so I understand that part now. There is no charge density. I figured there was something fishy there.
So I suppose I see how to apply a different mathematical approach here, but it's just a bit disappointing. Ah well.
So what is a delta function? And how else can I just integrate in...
Okay, first off, some quick background. I am a student in AP Physics C, and I like to think I generally have a good grasp of physics (I read about it outside the class). We just learned about Gauss's Law this week, and I have a good grasp of it. I understand how it can be used to simplify some...
