A non-uniform sheet charge is distributed along one-eighth of a spherical surfacelof radius 'a' as shown. The surface charge density is given by p=(7/sine) [C/m²]. Find the electric potential at the origin due to this charge distribution (with the standard assumption that the potential at infinity is zero).

The charge density on a disk of radius R = 11.6 cm is given by o = ar, with a = 1.46 μC/m³ and r measured radially outward from the origin (see figure below). What is the electric potential at point A, a distance of 44.0 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 R A
