A long, straight wire has fixed negative charge with a linear charge density of magnitude 3.6nC/m. The wire is to be enclosed by a coaxial, thin-walled non-conducting cylindrical shell of radius 1.5 cm. The shell is to have positive charge on its outside surface with a surface charge density σ that makes the net external electric field zero. Calculate σ.
