If the mass defect of \({ }_5 \mathrm{~B}^{11}\) is \(0.081 \mathrm{u}\), its average binding energy (in \(\mathrm{MeV}\) ) is

  1. A \(8.60\)
  2. B \(6.85\)
  3. C \(5.60\)
  4. D \(5.86\)
Verified Solution

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…
