(a) Consider a cylindrical conductor with radius a suspended inparallel over a conducting ground plane by a distance d in a medium with permittivity and conductivity. Calculate the capacitance per unit length between the two. You may assume that the distance dis much greater than the wire radius a. (d » a)
(b) Consider two parallel cylindrical conductors with radius aseparated by distance 2d. Calculate the capacitance per unit lengthbetween the two. You may assume that the distance d is much greaterthan the wire radius a. (d » a)
