A very long hollow cylinder has inner radius a and outer radius b and carries charge per unit length +a, where a is a positive constant with units C/m. A line of charge lies along the axis of the tube and has charge per unit length +a. (a) Calculate the electric field in terms of a and distance r from the axis of         the tube for       (i) r > a;       (ii) a < r < b;       (iii) r > b. (b) What is the charge per unit length on        (i) the tube's inner surface and       (ii) the tube's outer surface? Hint:This problem is really a series of conceptual questions but the answers are equations.  You must answer part (b) before you can answer the three sub-parts of part (a).
