The binding energy per nucleon of ¹0X is 9 MeV and that of ¹1X is 7.5 MeV. The minimum energy required to remove a neutron from ¹1X is:
Show Hint
Neutron separation energy equals the difference in total binding energies.
Updated On: Mar 20, 2026
- 7.5 MeV
- 2.5 MeV
- 8 MeV
- 0.5 MeV
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Total binding energies: B₁0 = 10 × 9 = 90MeV B₁1 = 11 × 7.5 = 82.5MeV
Step 2: Energy required: E = B₁0 - B₁1 + neutron energy
Step 3: E = 2.5MeV
