Q.
The binding energy per nucleon of $O^{16}$ is $7.97MeV$ and that of $O^{17}$ is $7.75\ MeV$. The energy (in $MeV$) required to remove a neutron from $O^{17}$ is
A) 3.52
B) 3.64
C) 4.23
D) 7.86
Explanation
(c) The equation is $O^{17} \rightarrow_{0}n^{1} + O^{16}$
$\therefore$ Energy required = B.E. of $O^{17} -$ B.E. of $O^{16}$
$= 17 \times 7.75 - 16 \times 7.97 = 4.23\ MeV$
