A conducting disk of radius R held at potential V sits in the x-y plane centered on the z-axis.
(a) Use the charge density for this system calculated in the text to find the potential everywhere on the z-axis.
(b) Ground the disk and place a unit point charge q₀on the axis at z = d. Use the results of part (a) and Green’s reciprocity relation to find the amount of charge drawn up from ground to the disk.
