There is a spherical conductor with radius A. It is at a power V0 and in infinity the electric potential V tends to zero. The Laplacian in spherical coordinates has the form..The independence of the problem with respect to the coordinates allows us to assume that V (r, θ, φ) = f (r), that is, V only has a radial dependence. What second-order differential equation satisfies f? Directly integrate the differential equation to find f (r) in the region r> a. Use the boundary conditions to determine integration constants. determine the electrostatic potential in the z> 0 region.
