WebA hollow sphere, with inner radius a and outer radius b, has a volumetric charge distribution p = kr^2, where r is the distance from the center of the sphere outwards and k is a known constant. Using Gauss's law, find the electric field at r < a, a < r < b, and r > b, and graph the electric field as a function of r. Web2. Rayleigh wave propagation on a sphere or a cylinder Conversely to the propagation of Rayleigh waves on a pl ane surface, the propagation of surface acoustic waves (frequency f = w/2 , wave number k) on a sphere or a cylinder, of radius a, is dispersive. The phase velocity V = w/k depends on the dimensionless
