The z-axis is the symmetry axis of a disk of radius R which lies in the x-y

Question:

The z-axis is the symmetry axis of a disk of radius R which lies in the x-y plane and carries a uniform charge per unit area σ. Let Q be the total charge on the disk.

(a) Evaluate the exterior multipole moments and show that

(b) Compute the potential at any point on the z-axis by elementary means and confirm that your answer agrees with part (a) when z > R.
