Physics Question on Nuclei
Fission of nuclei is possible because the binding energy per nucleon in them:
A
increases with mass number at high mass numbers
B
decreases with mass number at high mass numbers
C
increases with mass number at low mass numbers
D
decreases with mass number at low mass numbers
Answer
decreases with mass number at high mass numbers
Explanation
Solution
The graph shows that for high atomic mass nuclei, the binding energy per nucleon falls as the number of mass atoms increases.
Mass and number are reduced as a result of fission. Nuclei's stability will rise with a drop in mass number, allowing for the fission of heavier nuclei.
Therefore, the correct option is (B): decreases with mass number at high mass numbers
