# Coulomb potential from laplace's equation [closed]

How can I derive the equation for Coulomb Potential V(r) from the laplace's equation for electrostatic potential? $\nabla^2\psi=0$ (assuming spherical symmetry) I have no idea how i should start.

• Isn't this done in textbooks on the subject of E&M? – Kyle Kanos Feb 14 '17 at 11:07
