4-1. A thin dielectric rod of cross section A extends along the r-axis from * = 0 to a L. The polarization of the rod is along its length, and is given by P. = ax2 +b. Find the volume density of polarization charge and the surface polarization cbarge on ench end. Show explicitly that the total bound charge vanishes in this case. 4-1.
