Strong nuclear force and weak nuclear force

[Sagar Singh]

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.
