We all know that Poissson's equation in electrostatic is:
$$\nabla^2\phi=-\frac{\rho}{\epsilon_0}$$
My question is: why the solution, let's say for 1D, is not just double integral as follows:
$$\phi=\iint -\frac{\rho}{\epsilon_0} d^2x$$
which gives x square relation. But the actual solution comes from using Green's function and it gives the relation one over r (1/r). I need the connection between these things how they come to this and not that...
Thank you!
