Force between Point Charge and a Neutral Conducting Sphere

My question is simply an extension of this SE post; I don't understand why $q'+q''=0$ (both charges of hypothetical construct) for the sphere to be neutral. I'm trying to find a parallel between the ...

Green's function in a region between a conductor sphere and two charged spheres inside, with point charges inside of each

Please, help me. I have to find the Green's function in the following region, but I don't have any idea how to find it: I have a conducting spherical shell of radius a; in the center there are 2 ...

Why does concave mirror simultaneously form 2 images?

So in an experiment to find focal length of a concave mirror first we had to estimate its rough focal length. I kept an object at point which was beyond the focus in front of the mirror and got its ...

Boundary conditions for an infinite line charge and grounded conducing plane

I'm not asking for a solution to the problem, I'm confused about what I should set the boundary conditions to, it's obvious that $V=0$ at $z=0$ because of the grounded $xy$ plane, but I don't know ...

Applying method of images to magnetic dipoles

I want to apply the method of images to quasi-stationary calculate the 2D magnetic field distribution of a magnetic dipole and a half space with certain electrical properties (permeability, ...

Method of Images conundrum

My lecturer and I have found separately valid solutions to Poisson's equation in the region of interest for the following problem: Here is my interpretation of the boundary conditions: V(x,y,z \to ...
The classic image problem is that of a point charge $q$ held a distance $d$ above a grounded plane. The solution is this problem is to replace grounded plane by a charge $-q$ a distance $d$ below the ...
I have something puzzling me... Consider the standard problem of a grounded sphere and a charge $q$ outside: Do I need to describe it? Alright! Consider a grounded sphere, $V=0$, with radius $a$ ...
