The charge density on a disk of radius R = 12.6 cm is given by o = ar, with a = 1.34 μC/m³ and r measured radially outward from the origin (see figure below). What is the electric potential at point A, a distance of 36.0 cm above the disk? Hint: You will need to integrate the nonuniform charge density to find the electric potential. You will find a table of integrals helpful for performing the integration. X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. V R A

Separation of Variables: Cartesian coordinates A rectangular metal tube (its height extends from z = 0 to infinity) is placed on the xy plane. See Fig. 1. The side faces of the tube are kept at zero potential, V = 0, and the face of the base, supported on the xy plane, is maintained at a potential Vo (x.y). a) Calculate the potential inside the tube.b)Assume that the base plate, the one that rests on the xy plane, is conductive and maintained at constant potential, that is,Vo (x,y) = V.Calculate the potential inside the tube and determine the density of load o (x, y) on this plate, at z = 0. It might be useful know that: σ = - εo ∂V / ∂n
