Continuous Charge Distributions: Disk of Charge
•
Now let’s consider a uniformly-charged disk with area charge density σ. What is the
potential at any point on the axis of the disk?
V

•
What about the limit when you’re very close to the disk (i.e. x << R0)?
V
x
•
Does this kind of potential look at all familiar?
