Question

Write note on weak nuclear force

Answer 1

Answer:

In particle physics, the weak interaction, which is also often called the weak force or weak nuclear force, is the mechanism of interaction between subatomic particles that is responsible for the radioactive decay of atoms.

Explanation:

The weak force is carried by the W and Z bosons. ... By emitting an electrically charged W boson, the weak force changes the flavor of a quark, which causes a proton to change into a neutron, or vice versa. This is what triggers nuclear fusion and causes stars to burn

Weak nuclear force. The weak nuclear force (or just the weak force, or weak interaction) acts inside individual nucleons, which means that it is even shorter ranged than the strong force. It is the force that allows protons to turn into neutrons and vice versa through beta decay

Answer 2

Weak interaction, also called weak force or weak nuclear force, a fundamental force of nature that underlies some forms of radioactivity, governs the decay of unstable subatomic particles such as mesons, and initiates the nuclear fusion reaction that fuels the Sun. The weak interaction acts upon left-handed fermions—i.e., elementary particles with half-integer values of intrinsic angular momentum, or spin—and right-handed antifermions. Particles interact through the weak interaction by exchanging force-carrier particles known as the W and Z particles. These particles are heavy, with masses about 100 times the mass of a proton, and it is their heaviness that defines the extremely short-range nature of the weak interaction and that makes the weak interaction appear weak at the low energies associated with radioactivity.
