Question

Assertion (A) : Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion. Reason (R) : For heavy nuclei, binding energy per nucleon increases with increasing \(Z\) while for light nuclei, it decreases with increasing \(Z\).

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Both Assertion (A) and Reason (R) are false.

Hint:

Energy is released whenever the final nuclei have a higher binding energy per nucleon than the initial nuclei. \[ \text{Light nuclei} \Rightarrow \text{Fusion} \] \[ \text{Heavy nuclei} \Rightarrow \text{Fission} \]

Answer 1

The Correct Option is C
