Question

what is nutrino????and itz size???​

Answer 1

Answer:

Neutrinos are the smallest massive particles that we have currently measured and catalogued. The average electroweak characteristic size is r2 = n × 10−33 cm2 (n × 1 nanobarn), where n = 3.2 for electron neutrino, n = 1.7 for muon neutrino and n = 1.0 for tau neutrino; it depends on no other properties than mass .. ..

I hope this will help you,
