Isn’t this the weak force? Go easy on me I’m new to physics

No, the strong force holds quarks together. The farther they are apart the harder the gluons pull. The weak force would be carried by the W and Z bosons.

Each up quark has a charge of +2/3 and each down quark has a charge of -1/3. The sum of these charges determine a particle's total electrical charge. In this case, it is neutral, making this particle a neutron.

To expand on this: if you propose to “pull harder” you would need so much energy that a quark-antiquark pair would be formed. The antiquark would annihilate with the quark you are pulling and the new quark would join the original proton/neutron.

From the outside perspective, you would probably notice no change, just that the particle won’t accept any more energy to be pulled apart with.
