If the mass defect of ₅ ~B ¹¹ is 0.081 u , its average binding energy (in MeV ) is

Options

  1. A8.60
  2. B6.85
  3. C5.60
  4. D5.86

Correct answer

B. 6.85

Step-by-step solution

Given, m for ₅ ~B ¹¹=0.081 u Number of nucleons =11 aligned Binding energy & =931 m MeV & =931 0.081 & =75.411 MeV aligned Average binding energy aligned & = binding energy number of nucleons & = 75.411 11 & =6.85 MeV aligned
