A long straight conducting rod (or wire) carries a linearcharge density λ of + 2.0μC/m.
This rod is totally enclosed within a thin cylindrical shellof radius R, which carries a linear charge density of -2.0μC/m.
A) Describe how you would construct two Guassian surfaces tocalculate 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 eachof your Gaussian surfaces and for the resulting electric field ineach region.
