Vedclass · Answer

(B) Statement $1$ is true. Energy is released in both nuclear fission and nuclear fusion processes because the product nuclei are more stable (have higher binding energy per nucleon) than the parent nuclei.Statement $2$ is true. According to the binding energy per nucleon curve,for light nuclei (low $A$ or $Z$),binding energy per nucleon increases with $A$ (or $Z$),leading to energy release in fusion. For heavy nuclei (high $A$ or $Z$),binding energy per nucleon decreases with $A$ (or $Z$),leading to energy release in fission. Thus,Statement $2$ correctly explains why energy is released in both processes.

Statement $1$: Energy is released when a heavy nucleus undergoes fission and when light nuclei undergo fusion.
Statement $2$: For heavy nuclei,the binding energy per nucleon decreases as $Z$ increases. For light nuclei,the binding energy per nucleon increases as $Z$ increases.
