### 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 $a$ ...
