Two nuclei of mass number \( 3 \) combine with another nucleus of mass number \( 4 \) to yield a nucleus of mass number \( 10 \). If the binding energy per nucleon for the mass numbers \( 3 \), \( 4 \) and \( 10 \) are \( 5.6 \, \text{MeV} \), \( 7.4 \, \text{MeV} \) and \( 6.1 \, \text{MeV} \), respectively, then in the process,
