1. The problem statement, all variables and given/known data Find the general solution to Laplace's equation in spherical coordinates, for the case where V depends on on r. Do the same for cylindrical coordinnates assuming V depends only on r. 2. Relevant equations Laplace's Eq (spherical): 1/r^2 (d/dr)(r^2(dV/dr)) + 1/(r^2sin(theta))(d/dtheta)(sin(theta)(dV/dtheta)) + 1/(r^2sin^2(theta))(d^2V/dphi^2)) 3. The attempt at a solution Having it only depend on r should I just use the first term of the eq. Everything before the first plus. and, should I use this EQ for V: V = kq/r?
