Consider a disk with radius R and total charge Q. What are the electric potential and electric field at a distance z above the surface of the disk? (The point of interest here sits on the line through the center of the disk). What does E approach as z gets small compared to R? Similarly, what does it look like when z is large? Show that these results make sense.
