Suppose you design an apparatus in which a uniformly charged
disk of radius R is to produce an electric field. The field
magnitude is most important along the central perpendicular axis of
the disk, at a point P at distance 2.50R from the disk (Fig. a).
Cost analysis suggests that you switch to a ring of the same outer
radius R but with inner radius R/2.00 (Fig. b). Assume that the
ring will have the same surface charge density as the original
disk. If you switch to the ring, by what percentage will you
decrease the electric field magnitude at P?

For the next six problems, consider a uniformly charged disk of radius R. The total charge on the disk is Q. To find the electric potential and field at a point P (x>0) on the x-axis which is perpendicular to the disk with the origin at the center of the disk, it is necessary to consider the contribution from an infinitesimally thin ring of radius a and width da on the disk, as shown. What is the surface charge density...

Figure (a) shows a circular disk that is uniformly charged. The central z axis is perpendicular to the disk face, with the origin at the disk. Figure (b) gives the magnitude of the electric field along that axis in terms of the maximum magnitude Em at the disk surface. The z axis scale is set by zs = 41.0 cm. What is the radius of the disk?
