2. (10 pts.) Consider a sphere of radius R > 0 and its bounding cylinder with...
Problem 2 Consider a particle on a sphere of fixed radius r and V = 0 on the spherical surface. The particle is found in either of the following wavefunctions: Y1,1(0,0) or Y1,-1(0,0). a) What is the energy difference between the two possible wavefunctions? b) Determine the magnitude of angular momentum and its projection onto the z-axis for both wavefunctions. c) Do the energy and the magnitude of angular momentum change when the radius r of the sphere is increased?...
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...
