Problem #2: Two infinite long coaxial metal cylindrical tubes have radius a and b. Charges with uniform density o and are put on inner and outer tube, respectively. (a) Calculate the electric field Ē for three regions: s <a, a<s<b and $ >b. (b) Calculate the potential difference between two tubes Ves: calculate the capacitance per unit length (c) Calculate the electric energy stored per unit length between the inner and outer cylindrical tubes. (d) Using the boundary condition, Ezn - Ein = 0/€, calculate the surface charge density on the inner and outer surfaces of the outer tube
