The charge density on a disk of radius R = 11.2 cm is given by ? = ar, with a = 1.38 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. V
