There is a plot of binding energy per nucleon\[{{E}_{b}},\]against the nuclear mass M; A, B, C, D, E, F correspond to different nuclei. Consider four reactions: (i) \[A+B\to C+\varepsilon \] (ii) \[C\to A+B+\varepsilon \] (iii) \[D+E\to F+\varepsilon \] (iv) \[F\to D+E+\varepsilon \] Where \[\varepsilon \] is the energy released? In which reaction is e positive?     AIEEE  Solved  Paper-2009
