Yeah, they're just planes with normal vector in the z direction. I'm confused about the middle region...why wouldn't the "-4" be involved at all in the bounds. I have the same thing for the other two regions and understand why, but I don't understand why the middle region wouldn't be limited...

Why wouldn't the top section be V(6)-V(z), if for the other two regions the potential at the lower z-value was subtracted from that at the higher z-value [for V(z)-V(-4), z is "below" -4, and for V(-4)-V(6), -4 is "below" 6]?

I am, and I also got the same answer as you. This was the first page that came up when I tried to verify my answer online, and I recognized the problem immediately as Dr. D's.

Steve D. got you down?
