What is the evidence for strong nuclear force?
The exchange particle for the strong nuclear force is the pi meson. It has been produced by high energy collisions in particle accelerators, and detected by means of cloud chambers and bubble chambers. There is also very persuasive indirect evidence for the existence of the strong nuclear force, insofar as no atomic nuclei other than hydrogen could exist without that force, given that positively charged protons repel each other, and would not remain in close proximity in an atomic nucleus unless there was some force stronger than the electromagnetic force, holding them together.
Strong nuclear force and weak nuclear force. The strong nuclear force overcomes the repulsion of the positively charged protons in the nucleus, holding it together. The strong nuclear force also holds the quarks together that make up protons, neutrons, etc. The weak nuclear force is responsible for beta decay.
Strong nuclear force is the force that keeps the protons and neutrons in the nucleus of an atom. Being stronger than the electromagnetic force at very close distances, the strong nuclear force prevents the protons from repelling. Even more fundamentally, the strong nuclear force binds quarks together, which are the fundamental constituents of protons and neutrons.
Nuclear chemistry deals with the chemical reactions involving radioactive elements. Gamma radiation is due to the electromagnetic force, beta radiation is due to the weak nuclear force, and alpha radiation is due to the residual strong force (which you might call the strong nuclear force). So... if you didn't have the nuclear force, you wouldn't have alpha radiation.
The force of gravity the electromagntic force the strong nuclear force and the weak nuclear force are?
What evidence supports the contention that the strong nuclear force is stronger than the electrical interaction at short inter-nuclear distances?
Many atoms have nuclei consisting of several protons packed into an extremely small volume. Each proton has a positive charge, and since positive charges repel each other, the theory of electromagnetism says that these nuclei must not exist in a stable state. The fact that they do indeed exist leads us to believe that there is a force holding the protons together which must be stronger than the electromagnetic force. We call this force the…
The strong nuclear force affects matter by "building" it. Matter as we generally know it is composed of atoms. Atoms are built from protons, neutrons and electrons, and protons and neutrons are built from quarks. It is the strong nuclear force that binds the quarks and gluons together to make up the protons and neutrons. This is a straight forward way to explain how the strong nuclear force (strong interaction) affects matter.
