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 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 in each region.
