AIPMT PRELIMS 2005 Physics Nuclear Fission MCQ Question
Fission of nuclei is possible because the binding energy per nucleon in them:
increases with mass number at high mass numbers
decreases with mass number at high mass numbers
increases with mass number at low mass numbers
decreases with mass number at low mass numbers
Correct Answer
Detailed Explanation
Fission occurs in heavy nuclei where the binding energy per nucleon decreases with increasing mass number, making them less stable and more likely to split into smaller, more stable nuclei.
