Nuclei - Result Question 37
38. Fission of nuclei is possible because the binding energy per nucleon in them [2005]
(a) increases with mass number at low mass numbers.
(b) decreases with mass number at low mass numbers.
(c) increases with mass number at high mass numbers.
(d) decreases with mass number at high mass numbers.

Answer:
Correct Answer: 38. (d)
Solution:
- (d) B.E. per nucleon is smaller for lighter as well as heavier nucleus. But fusion reaction occurs for small mass number nuclei and fission reaction occurs for larger mass number nuclei to attain reaction binding energy per nucleon.
