Doubt regarding proof of Earnshaw's Theorem using Gauss's theorem
While proving Earnshaw's theorem using Gauss's theorem, we consider a small sphere surrounding our test charge, and apply Gauss law on this sphere, stating that field from all external charges must ...

If we have a net negative charge in a spherical conductor, why negative charges goes to the surface?
So imagine that we have a set of net negative charges, in physics books they said that this set of charges goes to the surface because they repel each other in such a way that this reach to an ...

Why charges should go to the surface of conductor? [duplicate]
How can we show that charges should go to the surface of a conductor, assuming that system should minimize its energy? (With
no additional assumptions and maybe using variation method!)

Earnshaw's Theorem in Chemical Bonds
Earnshaw's theorem says that:
A collection of point charges cannot be maintained in a stable stationary equilibrium configuration solely by the electrostatic interaction of the charges.
I also know ...

Unstable equilibrium due to an arbitrary electrostatic configuration
Suppose n charges are put in an arbitrary electrostatic configuration and a small test charge is placed at a null point (i.e., where $\vec{E}=0$ ) of the configuration.
The task is to show that the ...

Why charges reside on the surface on conductor? [duplicate]
In a hollow conductor and in a spherical shell the charges reside on its surface and there is no electric field inside it.Please tell me the reason behind it.

Why are excess charges in a conductor at the surface?
I’ve been told that coulomb repulsion pushes excess electrons to the surface of a conductor (i.e. sphere) electrostatic equilibrium, and this symmetry causes the net electric field inside to be zero. ...
