Strong nuclear force and weak nuclear force

In summary, the strong nuclear force is short-range and mediated by the gluon, while the weak nuclear force is mediated by the W/Z boson. These forces are ranked in increasing coupling strength as follows: weak force, electromagnetic force, and strong force. It is recommended to ask specific questions on PF rather than seeking general information, and to refer to Wikipedia articles on these forces for further understanding.

Hi There!
i am little bit confused in between existence of strong and weak nuclear force, can someone please explain about these forces and about their existence

Strong nuclear force is extremely short ranged, and is mediated by the gluon. The weak nuclear force is mediated by the W/Z boson. In order of increasing coupling strength it goes as - Weak force, Electromagnetic Force, Strong Force.

PF is a forum, not an encyclopedia. It works much better if you ask specific questions and use other sites for general information. I suggest looking at the wikipedia articles for both forces and then coming back to PF with specific questions.

1. What is the difference between strong and weak nuclear force?

The strong nuclear force is responsible for holding the nucleus of an atom together, while the weak nuclear force is responsible for radioactive decay.

2. How do strong and weak nuclear forces interact with each other?

The strong nuclear force is much stronger than the weak nuclear force and is responsible for keeping the protons and neutrons in the nucleus together. The weak nuclear force, on the other hand, is responsible for changing one type of particle into another through radioactive decay.

3. Can you give an example of a phenomenon that is influenced by strong and weak nuclear forces?

An example of a phenomenon that is influenced by both strong and weak nuclear forces is nuclear fusion, the process that powers the sun and other stars. The strong nuclear force allows for the fusion of two or more nuclei to form a larger nucleus, while the weak nuclear force is responsible for the decay of unstable nuclei.

4. Are strong and weak nuclear forces always attractive?

No, strong and weak nuclear forces can also be repulsive. The strong nuclear force can be repulsive at very short distances between particles, while the weak nuclear force can be repulsive in certain types of radioactive decay.

5. How were strong and weak nuclear forces discovered?

The existence of strong and weak nuclear forces was inferred through experiments and observations of nuclear reactions. The theories of these forces were developed by physicists such as Enrico Fermi and Hideki Yukawa in the early 20th century.
