A long metal cylinder with radius a is supported on an insulating stand on the axis of a long, hollow, metal tube with radius b. (Note: b>a) The positive charge per unit length on the inner cylinder is $\lambda$, and there is an equal negative charge per unit length on the outer cylinder. Part A Calculate the potential V (r) for $r < a$. (Hint: The net potential is the sum of the potentials due to the individual conductors.) Take $V = 0$ at $r = b$.
