Acylindrical conductor with a circular cross section has a radius a and a resistivity p and carries a constant current i. (take the current to be coming out of the page when the cross-sectional view of the conductor is in the plane of the page.) for the following questions, express your answer in terms of the variables i, a,p, and appropriate constants (u0,e0, and pi).a) what is the magnitude of the electric field vector e at a point just inside the wire at a distance a from the axis? b) what is the magnitude of the magnetic field vector b at the same point? c) what is the magnitude of the poynting vector s at the same point? d) what are the directions of these three vectors?
