Use Gauss’ law to find Ē in all regions. Clearly indicate the choice of a proper Gaussian surface for each region and how the law is applied

Problem 1) a) [10 marks] Volume charge is distributed in the cylindrical coordinate system the following charge densities: (r,9,z) with Py=+por Pr=0 Pr= Po forr <R , for R,<r<R2 , and for r>R2 00 where po>0, Ry, and R, are constants. Use Gauss’ law to find Ē in all regions. Clearly indicate the choice of a proper Gaussian surface for each region and how the law is applied.
