Consider two long, coaxial, and thin cylindrical shells. The inner shell has the radius of R1 and the outer of R2. The inner shell has a certain negative charge per unit length and the outer shell has a positive charge per unit length. The positive charge is twice as big in magnitude as the negative charge. Both charges are distributed uniformly over the surface. Determine the electric field and the electric potential as functions of the distance away from the axis of the shells. Make qualitative plots of these functions. Note that a derivative of ln x is 1/x.
