Suppose, a charged disk of radius R=16m is lying on the xz plane as shown in the figure. The charge density of the disk is σ = 9nC/m2. The total charge of the disk is 7.234×10-6C. Point s is located along a line perpendicular to the disk and that goes through the center of the disk. Which is happened to be the y axis in this problem.
