Use Gauss' law to determine an equation that represents the electric field in the radial direction caused by a volumetric charge distribution with density : 4-r Pv(r): You should note that the volumetric charge density extends to infinity. In using Gauss' law, you will have to integrate to a radius of r de determine the charges enclosed within the Gaussian surface. You'relikely to have to use the method of integration by parts. When you determine the enclosed charges, you'll probably notice that Qene = q for r = co, and Qene 0 for r = 0. %3!
