ECE 107, QUIZ 3 Monday, March 1, 2010 Name : ___________________________________ GRADING: 1) 30 points ______ 2) 30 points ______ 3) 10 points______ 4) 30 points_____ Total (100 points) _________________ 1) Consider a structure consisting of two coaxial infinitely long (along the z axis) cylinders of given radii a and b with ba (Fig. 1). The space between ra and rb is filled uniformly with a given static volumetric charge density v . There is no charge for or . The permittivity and permeability of the entire space are as in vacuum. Find the electric field E due to the charge density v everywhere in space (i.e. for , arb , and ). 2) The charge distribution in item 1 now moves with a constant velocity v along the z axis to produce a static volumetric current density v J . Give v J in terms of v and v . Find the magnetic field H due to the current density v J everywhere in space (that is, for
