Description: An infinite charged rod sits at the center of an infinite conducting cylindrical shell.

Description: An infinite charged rod sits at the center of an infinite conducting cylindrical shell. Determine the field between the rod and shell, the field outside the shell, and the surface charge on the inner and outer surfaces of the shell. An infinitely long conducting cylindrical rod with a positive charge per unit length is surrounded by a conducting cylindrical shell (which is also infinitely long) with a charge per unit length of and radius , as shown in the figure. From the axis of the cylindrical rod?
