Could someone please help, i think this is gauss's law but im not sure how to answer it as they give me a wave equation and i dont know how to put magnetic field in as well. Help would be much appreciated(adsbygoogle = window.adsbygoogle || []).push({});

Question

suppose that an appropriate device is used to genereate an osccilating electric field in a limited region of the xy plane of a Cartesian Reference frame ,as described by

E(r,t) ezE0sin(wt) for

√x(squared)+Y(squared) <(equal ) R

a) determine the expression for the magnetic field induced by this electric field in the xy plane at a distance r<R from the origin

b)at a distance r>R from the origin assuming that in the 1st approximation E=0 in this region

c) discuss if u would expect an induced an electric field to also be present in the region r>R of xy plane
