Question
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 - I:Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. andStatement - IIFor heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei it decrease with increasing Z.Statement −1 is false, Statement −2 is true.Statement - 1is true, Statement −2 is true; Statement −2 is correct explanation for Statement-1.Statement −1 is true, Statement −2 is true; Statement −2 is not a correct explanation for Statement-1.Statement −1 is true, Statement −2 is False.
Solution
Statement −1 is true, Statement −2 is true; Statement −2 is not a correct explanation for Statement-1.
Explanation:
Statement 1 is true because energy is indeed released when heavy nuclei undergo fission or light nuclei undergo fusion. This is a fundamental principle of nuclear physics.
Statement 2 is also true. For heavy nuclei, the binding energy per nucleon does increase with increasing atomic number (Z). This is because the more protons there are in a nucleus, the stronger the nuclear force needs to be to keep the nucleus together, which means more energy is required. For light nuclei, the binding energy per nucleon decreases with increasing Z. This is because the nuclear force is not as strong in lighter nuclei, so less energy is required to keep the nucleus together.
However, Statement 2 is not a correct explanation for Statement 1. The release of energy in nuclear fission or fusion is not directly related to the change in binding energy per nucleon with increasing Z. Instead, it has to do with the difference in binding energy between the initial and final states in the nuclear reaction.
