I am just a man who has an insatiable desire for knowledge.

"For the rest, brethren, whatever is true, whatever is worthy of reverence and is honorable and seemly, whatever is just, whatever is pure, whatever is lovely and lovable, whatever is kind and winsome and gracious, if there is any virtue and excellence, if there is anything worthy of praise, think on and weigh and take account of these things [fix your minds on them]."~ Philippians 4:8

@MichaelBrown Yes, I have actually; but I wasn't sure if I need it. So, should I generate a Gaussian plate, infinite in size, and place it between the two sheets? Then, find the magnitude of the electric field from sheet, and multiply it by two?

To be frank, the textbook you have provided appears to be a little advanced. Seeing as I am only in a undergraduate Physics II course, I am not sure it will be very helpful at the moment. Notwithstanding, I still glad you did provide me with a link, because the book does look interesting, and I'd like to read it someday.

comment Higher To Lower Electric Potential
@MichaelBrown Actually, I have one more question. I was able to answer the question I originally posed, except for part (b). I thought, because the electric potential energy was increasing at that point, that the electric potential at that point would be higher. After all, electric potential is defined one way as, "the amount of electric potential energy that a unitary point charge at that location would have." So, if the electron has more PE at the final position, wouldn't that mean the electric potential was greater at that final position too?

Thank you for the explanation. I think that was the root of my confusion; what they said in the orignal problem I posted seemed odd, that potential energy is increasing, but electric potential was becoming more negative.

@MichaelBrown So, even though we have a positive increase in potential energy for a negative test charge, the change in electric potential could be negative because of the sign negative test charge?

Yes, I believe so. Just one question, if I push a negative test charge near a negative source charge, the test charge will be gaining potential energy, and that potential energy will be positive, right? Alternatively, if I move a negative test charge near a positive source charge, making sure it doesn't accelerate towards it, it will loss potential energy, showing up as a negative potential energy, right? And the mathematics will show that these are true? I guess the root of my problem is seeing a generalized situation, and the mathematics that accompany it.

comment Higher To Lower Electric Potential
Sorry for the inundation of questions. I've heard electric potential being described as being "the measure of potential energy per unit charge." From this, I have developed the understanding that electric potential is a scalar that is assigned a different value at every point in an electric field.It almost seems like a conversion factor. It's how much potential energy a charged particle could possession if it were there. It's a potential of a potential. Again, sorry for all of the comments. I hope you can help me.

Also, is it true that if a charge has negative electric potential energy, then it is not necessary that it has lost that energy. In other words, negative electric potential energy can mean a gain in that sort of energy?

comment Higher To Lower Electric Potential
I understand it, for the most part; one bit I don't quite understand, however, is this, "negative charge that rolls 'down this potential hill'." I keep reading allusions about this "potential hill" analogy, but I can't find an actual source of it. Do you know of any online articles that treat this analogy?
