At this length scale the position of quarks is not a very well-defined concept any more. You can still talk about the energy scale, however. The strong interaction stays stronger up to energies way beyond the reach of current experiments. It is expected that the strong, weak and electromagnetic interaction all get the same strength for some extremely high energy, and behave like a single interaction beyond that. This concept is called Grand Unification.Hami Hashmi said:So if two quarks got to a distance of <<10^-18 m
Yes, the strong nuclear force is indeed stronger than the weak force. The strong nuclear force is responsible for binding protons and neutrons together to form the nucleus of an atom, while the weak force is responsible for radioactive decay.
The strong nuclear force is approximately 100 times stronger than the weak force. This is why it is able to hold the nucleus of an atom together against the repulsive forces of the positively charged protons.
The strong and weak forces are fundamentally different from electromagnetic and gravitational forces. While electromagnetic and gravitational forces act over long distances, the strong and weak forces only act over extremely short distances within the nucleus of an atom.
There have been attempts to unify the strong and weak forces into a single force, known as the electroweak force. However, this theory is still a work in progress and has not been fully confirmed.
The strong nuclear force is crucial for the stability of an atom. Without it, the positively charged protons in the nucleus would repel each other and the atom would not exist. The strength of the strong force ensures that the nucleus remains stable and the atom is able to exist in its current form.
