A long straight conducting rod (or wire) carries a linearcharge density λ of +2.0μC/m. This rod is totallyenclosed within a thin cylindrical shell of radius R, which carriesa linear charge density of -2.0μC/m.
A) Describe how you would construct two 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 field ineach region.
