Do the task in Prob. 12 if U1 = 220 V and the outer cylinder is grounded, U2 = 0.
Data from Prob. 12
Find the potential and complex potential between the coaxial cylinders of axis 0 (hence the vertical axis in space) and radii r1 = 1 cm, r2 = 10 cm, kept at potential U1 = 220 V and U2 = 2 kV, respectively.
