The nuclear particle having no mass and no charge, but only spin is - (1) proton (2) neutrino (3) meson (4) electron
by

1 Answer

Answer :

(2) neutrino Explanation: Neutrinos do not carry electric charge, and have mass quite small, though nonzero. Their mass is tiny even by the standards of subatomic particles. They are electrically neutral, weakly interacting elementary subatomic particles with half-integer spin.
