A thin-walled cylindrical tube of length 22 and radius R has a uniform charge per unit area o on its outer surface. Derive an expression for the electrostatic potential at the point on the axis of the cylinder midway between the ends, assuming that the zero of potential is at infinity. Then simplify this expression in the case where R = 3L, and give your result by entering a numerical value and an exponent in the expression below:
