A long straight conducting rod (orwire) carries a linear charge densityλof +2.0μC/m. This rod is totally enclosed within a thin cylindrical shell of radius R, which carries alinear charge density of - 2.0μC/m.
A) Describe how you would constructtwo Gaussian surfaces to calculate the electric field: one outside the cylindrical shell, and the other between the shell and the wire,to apply Gauss’ Law
B) Write the expression for the electric flux threading each of your Gaussian surfaces and for the resulting electric fieldin each region
