Confusions/Doubts about EMF & charge difference

[werunom]

Hello.

Down below I have listed few questions. I think all of them deal with the same confusion/doubt that I have about EM force [that is why I have clubbed them in one post].
Because of the basic confusions/doubts, I might not have framed the questions clearly. Please correct where ever I have gone wrong.

1. The EM force [EMF] is directly proportional to product of charges and inversely proportional to the distance between them. So if that is the case,
>If there is an electron and a proton, the EM force binds them together. So can I say that if there are two protons in the nucleus and a single electron, this electron would be much closer to the nucleus than an electron bound to a single proton?
> going by this, what is the factor which decides the distance between these oppositely charged particles/collections? If distance is zero, then EMF is infinite. This cannot be true since EMF is observable only within a particular range, below which the strong forces are dominant. So what is the reason for this distance factor?

2. If I consider a setup of an electron revolving around a nucleus of two protons, then there is a room for another electron as well. Because, the ion has a net positive charge and it will attract electrons. So it appears that the net charge of the ion has something to do with EMF with which it attracts the electrons.
What is the relationship between charge difference between two charged bodies & the EMF that results because of that? There should be some connection between charge satiation and residual EMF.

3. Hypothetically speaking, an electron has –e and a quark has +1/3e. So if there happens to be a stray quark [hypothetical], is it possible for EMF to exist between these two and because of which the electron pairs with a quark?
And, if that is the case, am I correct in saying that a quark repels another quark electromagnetically; but the strong force overcome this and binds three of them to form a nucleon?

Let me know if I have to explain in detail or paraphrase my questions, if they haven’t been put clearly.
Thanks.

The EMF between two charged particles is described by Coulomb's Law, which states that the force is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them. Thus, if there are two protons and one electron in a nucleus, the electron will be much closer to the protons than an electron bound to a single proton because the EMF between the two protons and the electron will be stronger than the EMF between the electron and the proton. The distance between two oppositely charged particles or collections of particles is determined by the product of their charges and the strength of their mutual EMF. If the EMF between them is strong enough, they will be pulled together until they reach a certain distance at which their EMF is balanced by other forces, such as the strong nuclear force.Yes, it is possible for an electron and a quark to be bound together electromagnetically. However, the strong nuclear force is much stronger than the EMF and will generally overpower it. Thus, three quarks will be held together by the strong force to form a nucleon.
