Q. The binding energy per nucleon of C12 is 7.68 MeV and that of C13 is 7.47 Mev. The energy required to remove one neutron from C13 is

(a) 495 MeV

(b) 49.5 MeV

(c) 4.95 MeV

(d) 0.495 MeV

Click to See Answer :
Ans: (b)
Sol: C13 + Energy → C12  + n

Hence Energy required to remove one neutron = difference in total B.E

= 13 × 7.47 −12×7.68

= 97.11 −92.16

= 4.95 MeV
