An infinite conducting cylindrical shell of outer radius r1 = 0.10 m and inner radius r2 = 0.08 m initially carries a surface charge density σ = -0.35 μC/m2. A thin wire, with linear charge density λ = 1.1 μC/m, is inserted along the shells' axis. The shell and the wire do not touch and these is no charge exchanged between them.
a) What is the new surface charge density, in microcoulombs per square meter, on the inner surface of the cylindrical shell?
b) What is the new surface charge density, in microcoulombs per square meter, on the outer surface of the cylindrical shell?
c) Enter an expression for the magnitude of the electric field outside the cylinder (r > 0.1 m), in terms of λ, σ, r1, r, and ε0.
