A very long conducting cylinder of radius a carries a uniform surface charge density ρsa . It is enclosed by another conducting cylinder of inner and outer radii b and c, respectively. Calculate the electric field intensity everywhere in space.
What is the charge density on the inner surface of the outer conductor? What is the charge density on the outer surface of the outer conductor? What happens to the charge and the fields when the outer surface of the outer conductor is grounded?
Are all solids able to conduct an electric current? Explain
