    During a negative beta decay,
    (a) an atomic electron is ejected
    (b) an electron which is already present within the nucleus is ejected
    (c) a neutron in the nucleus decays emitting an electron
    (d) a proton in the nucleus decays emitting an electron.
    digAnsr:   c
    Ans : (c) a neutron in the nucleus decays emitting an electron
    Negative beta decay is given as
    `` n\to p+{e}^{-}+\stackrel{¯}{\nu }``
    Neutron decays to produce proton, electron and anti-neutrino.
