If the mass defect of \({ }_5 \mathrm{~B}^{11}\) is \(0.081 \mathrm{u}\), its average binding energy (in \(\mathrm{MeV}\) ) is
- A \(8.60\)
- B \(6.85\)
- C \(5.60\)
- D \(5.86\)
Answer & Solution
Correct Answer
(B) \(6.85\)
Step-by-step Solution
Detailed explanation
Given, \(\Delta m\) for \({ }_5 \mathrm{~B}^{11}=0.081 \mathrm{u}\) Number of nucleons \(=11\) \[ \begin{aligned} \text { Binding energy } & =931 \times \Delta m \mathrm{MeV} \\ & =931 \times 0.081 \\ & =75.411 \mathrm{MeV} \end{aligned} \] Average binding energy…
