Question

The atomic mass of `._(7)N^(15)` is `15.000108 "amu"` and that of `._(8)O^(16)` is `15.994915 "amu"`. The minimum energy required to remove the least tightly bound proton is ( mass of proton is `1.007825 "amu"`)
A. `0.013018eV`
B. `12.13 MeV`
C. `13.018 MeV`
D. `12.13 eV`

Answer 1

Correct Answer - B
`Delta m=m_(p)+m_("nitrogen")-m_("oxygen")`
energy required `= Deltamxx931.5 MeV`
