Professor PC Thomas Classes · Answer

(a) : (A) → (P,T); (B) $ightarrow(\mathrm{R}, \mathrm{T})$; (C) $ightarrow(\mathrm{Q})$; (D) $ightarrow(\mathrm{S})$. \ For $\alpha$-decay, electrostatic repulsion must be greater than nuclear force, this happens, when nucleus is large. In $\beta^4$ decay positron is emitted and a proton is changed to neutron. In $\beta^{-}$decay a neutron is changed to a proton. In $K$ capture, a proton is changed to a neutron.
