NEET Physics Nuclear Forces MCQ Question
Type: MCQ-conceptual-Medium-Class 12
What is the primary reason for energy release when a very heavy nucleus breaks into two smaller nuclei?
A
Higher binding energy per nucleon in smaller nuclei
B
Greater number of protons in the smaller nuclei
C
Increased neutron-proton ratio in smaller nuclei
D
Decreased neutron-proton ratio in smaller nuclei
Correct Answer
Option A
Detailed Explanation
The binding energy per nucleon of a nucleus with a smaller mass number (e.g., A = 120) is higher than that of a very heavy nucleus (e.g., A = 240), leading to energy release.
