At 2.5 femtometer away from a quark the strong force is said to significantly loose power and become insignificant. At how many femtometers does the strong force completely loose any amount of tug?
mfb said:As usual, there is no single point where it gets exactly 0. But the force is decreasing so quickly that it gets completely irrelevant (and small compared to the electromagnetic force, for example) just some femtometers away.
The_Duck said:Yes. Just keep in mind that the numbers on the y-axis don't mean anything; it's the shape of the graph that is meaningful.
The strong force is one of the four fundamental forces of nature. It is responsible for holding the nucleus of an atom together by binding protons and neutrons together through the exchange of particles called gluons.
Femtometers (fm) are a unit of measurement used in particle physics to describe the size of subatomic particles. The strong force is only effective within a range of 1-3 femtometers, known as the "strong force range."
If the distance between particles is greater than the strong force range, the strong force will cease to exist and the particles will no longer be bound together. This is why the nucleus of an atom can be split in nuclear reactions, as the particles are separated beyond the strong force range.
There is no exact distance at which the strong force ceases to exist. The range of the strong force can vary depending on the energy levels and number of particles involved.
The strong force is distinct from the other fundamental forces (electromagnetic, weak, and gravitational) and is responsible for binding particles together within the nucleus of an atom. However, at high energy levels, the strong force can merge with the other forces, creating a unified force called the "grand unified force."
