Answer :
A fundamental particle with no electric charge and a spin of one-half is called an electron neutrino (v).
Explain about the electron neutrino?
The subatomic particle known as a neutrino resembles an electron in many ways, but it differs in that it lacks an electrical charge and has a very small mass that may even be zero. One of the cosmological particles with the highest density is the neutrino. However, they are exceedingly difficult to find because they barely interact with matter.
Small, almost massless particles known as neutrinos move at speeds close to light. They are phenomenally common in the universe and can move through lead as readily as we do through air. They are the product of intense astronomical events like exploding stars and gamma ray bursts.
A flat recoil energy spectrum is the result of monoenergetic electron neutrinos scattering from electrons.
