Arectangular pipe, running parallel to the z-axis (from -0o to +o0), has three grounded metal sides, at y 0, y = a, and x = 0. the fourth side, at x = b, is maintained at a specific potential vo(y) i)develop a general formula for the potential within the pipe ii)find the potential explicitly, for the case vo(y) = vo (a constant) hint: you will need to solve laplace's equation making use of cartesian coordinates.
