    Can we make use of Greens function if there are no charges?

    never mind I have found out where I was missing. your hint was very helpful. but there is one further question that pops out here. say we have written the greens function for such a problem in cylindrical coordinates, on the surface and considering the ##F_s = E_0## a constant, we arrive at the...

    Can we make use of Greens function if there are no charges?

    Lets say we have the following conditions given and we want to find the greens function in cylindrical coordinates: ## \nabla^2 \phi =0## this will eliminate the volume charge term in the equation for ##\phi## we also have that ##\phi|_{s} = F_{s}(\rho , \phi)## at the surface...

    Can we make use of Greens function if there are no charges?

    I can't think of a situation where we can utilize greens function without the presence of a point charge. lets consider the following equation: \Phi=\frac{1}{4\pi \epsilon} \int dv \rho(x')G_{N} (x,x')+ \frac{1}{4\pi} \int da F_{s}(\rho , \phi) G_{N} + <\phi>_S Here we see that a volume...
