Mass Defect & Binding Energy
This question contains Statement- 1 and Statement- 2. Of the four choices given after the statements, choose the one that best describes the two statements:
Statement- 1:
Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. Statement- 2:
For heavy nuclei, binding energy per nucleon increases with increasing while for light nuclei it decreases with increasing
Show answer and solution
Answer: (d)
- Statement 1: true. Fission of heavy nuclei and fusion of light nuclei both increase , so energy is released.
- Statement 2: false. For heavy nuclei decreases with increasing , and for light nuclei it increases; the statement has it reversed.
- So the answer is (d).
