and positive z pointing out of the page. A rectangular box sits aligned with the x, y, and z axes, with one corner at the origin, and the opposite corner at < 0.5, 0.4, 0.3 > meters. (In other words, the box is 0.5 meters long in the x direction, 0.4 meters tall in the y direction, and 0.3 meters deep in the z direction). Along the left side of the box (the part on the y-z plane), the electric...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
