If the binding energy per nucleon in 3Li7and2He4nuclei are respectively5.60 MeVand7.06 MeV, then the energy of the proton in the reaction 3Li+p→22He 4is

Options:

Answer:
D
Solution:

Applying principle of energy conservation.

Energy of proton = total BE of2 α-energy ofLi7

=8×7.06-7×5.6

=56.48-39.2=17.28 MeV
