Along straight conducting rod (or wire) carries a linear chargedensity λ of +2.0μC/m.This rod is totally enclosed within a thin cylindrical shell of radius R, which carries a 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 thewire, 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.
