Nature of the force between 2 protons when sharing an electron.

In summary, the lecture discusses the attractive force between two protons when they share an electron and how the electromagnetic force overpowers this force when the protons are far apart. The name of this force is the proton-motive force and it is considered a fundamental force, just like the electromagnetic force. The electron plays a crucial role in binding the protons together by spending time between them and attracting them, overcoming their electric repulsion.

Hi :)

In this lecture (), susskind talks about attractive the force between two protons due to them sharing an electron and tunelling etc. He also describes how the electromagnetic force overwhelms this force when the protons are far apart.

What is the name of this force? And why do I keep thinking that it's none of the fundamental forces?
So what's the nature for this force in terms of the 4? Or what? :)

Proton-motive force, I believe is the name.

I haven't watched the lecture, but the only relevant force is the electromagnetic force. Two protons can be bound together by sharing an electron because the negatively charged electron spends a lot of time in between the two positively charged protons. Each proton is (electrically) attracted to the electron, and this overcomes the electric repulsion between the two positively charged protons.

Ok thanks :) Makes sense now.
 

What is the nature of the force between 2 protons when sharing an electron?

The force between two protons when sharing an electron is known as the electromagnetic force. This force is responsible for holding the positively charged protons together despite their repulsion.

How does the sharing of an electron affect the force between two protons?

When two protons share an electron, they become electrically neutral and the electromagnetic force becomes stronger. This is because the shared electrons create a balance between the positive charges of the protons, making the force between them more stable.

Does the distance between two protons affect the force when sharing an electron?

Yes, the force between two protons when sharing an electron decreases as the distance between them increases. This is because the electromagnetic force is an inverse square law, meaning that it decreases exponentially as the distance between the particles increases.

What other factors can affect the force between two protons when sharing an electron?

The force between two protons when sharing an electron can also be affected by the presence of other particles or fields. For example, if there are other charged particles nearby, their fields can interact with the electromagnetic force between the protons and alter its strength.

Is there a limit to the force between two protons when sharing an electron?

Yes, there is a limit to the force between two protons when sharing an electron. This limit is known as the strong nuclear force, which is the strongest force in nature. It only comes into play when the particles are extremely close together, such as in the nucleus of an atom.
