Problem is as follows:
(Figure 1) shows two very large slabs of metal that are parallel and distance l apart. The top and bottom surface of each slab has surface area A. The thickness of each slab is so small in comparison to its lateral dimensions that the surface area around the sides is negligible. Metal 1 has total charge Q1=Q and metal 2 has total charge Q2=2Q. Assume Q is positive.
The Attempt at a Solution
So for working through this problem, I've already determined 2 & 4, those were zero which is pretty easy, and I think I know the general path to follow for this
Only been working on one so far, just need some guidance on where to move but so far its
Then I imposed a gaussian surface over the upper half of the top slab in order to get the E-field at 1, I chose a rectangle for this
I know its the right path, and sorry if I didn't write it out perfectly, just not sure how to handle the area of the rectangle I imposed over 1.
