Is the Force Between Two Protons Weaker Than Between Two Neutrons in Nucleons?

In summary, the strong nuclear force treats all nucleons equally, regardless of their electric charge. This means that the force required to separate two neutrons is the same as that required to separate two protons. The electromagnetic interaction between two protons is repulsive, but the strong force overpowers this repulsion to keep the protons together in the nucleus. There are no bound states for two protons or two neutrons, making it difficult to determine the exact amount of force required to separate them.

My question is whether the force between two protons is slightly less than the force between two neutrons as you'd expect from the electrostatic repulsion or does the strong nuclear force somehow treat all nucleons such that they have the same force acting between them? I'd really appreciate some help, thank you

Of course the electrostatic forces are much weaker- I'm just interested in knowing if there indeed is a slight difference as one might think

The strong interaction doesn't care about electric charges. You have two independent interactions, and for two protons the electromagnetic interaction is repulsive.

This is a very interesting question. Does this mean that the amount of force required to separate two neutrons is the same as that required to separate two protons? Or can the protons be separated with slightly less force, like, the the amount required for neutrons minus something for the strength of the magnetic repulsion between the two protons?

Exactly what I want to know :D

which would imply what @LURCH said, correct?

There is no bound state for two protons or two neutrons and "distance" becomes a problematic concept as well.

So its very hard to say. Alright, I can take that as the best answer which can possibly be given- Thank you very much :D

Does an alpha particle not count as a bound state?

Alpha particle is 2 neutrons+2 protons. I think he means there are no two separate nuclei which have only 2 protons or two neutrons

The strong force works between proton in the nucleus. The energy to keep them together came from Δm of mass of nucleus and Total mass of proton and neutron, the Δm was converted to energy by the equation E = Δm.c² to keep proton in the nucleus stay together

Right. If there would be bound states "2 protons" and "2 neutrons" (separately) then the former could be bound weaker.
 

What is the definition of force between two nucleons?

The force between two nucleons refers to the attractive or repulsive force that exists between two protons or two neutrons within the atomic nucleus.

What causes the force between two nucleons?

The force between two nucleons is caused by the strong nuclear force, which is one of the four fundamental forces of nature. This force is responsible for binding protons and neutrons together in the atomic nucleus.

How does the force between two nucleons affect the stability of an atom?

The force between two nucleons is crucial for the stability of an atom. It is the strong nuclear force that overcomes the repulsive force between positively charged protons, thus keeping the nucleus intact and preventing it from breaking apart.

Can the force between two nucleons be measured?

Yes, the force between two nucleons can be measured through experiments such as scattering experiments or nuclear reactions. However, due to its extremely short range, it can only be measured indirectly.

Does the force between two nucleons vary depending on the types of nucleons involved?

Yes, the force between two nucleons can vary depending on the types of nucleons involved. For example, the force between two protons is slightly weaker than the force between a proton and a neutron. This is due to the difference in their charges and the fact that protons have a slightly smaller mass than neutrons.
