The mass defect of a nucleus is 0.01 u. What is the binding energy per nucleon if the nucleus has 20 nucleons?
Q1. The mass defect of a nucleus is 0.01 u. What is the binding energy per nucleon if the nucleus has 20 nucleons?
Answer: 0.465 MeV
Explanation: Binding energy = 0.01 u × 931 MeV/u = 9.31 MeV. Per nucleon, it's 9.31/20 = 0.465 MeV. Other options miscalculate.
