Hi,
if we only have an electrostatic potential given. How to calculate the charge density? I know of course Maxwell equation, here without any time dependence, but I missed always some further specifications, or I forget something important thanks greetings

Use Laplace's equation (derived from Gauss's Law):
[tex]\nabla^2 \Phi = \rho / \epsilon_0[/tex]

That's Poisson, not Laplace.
