Nucleus: Practice Problem & Solution
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): \(\text{Fe}^{56}\) nucleus is more stable than \(\text{U}^{235}\) nucleus. Reason (R): Binding energy of \(\text{Fe}^{56}\) nucleus is more than the binding energy of \(\text{U}^{235}\). In the light of the above statements, choose the correct answer from the option given below.
Solution Explained:
To solve this problem, we apply the core principles of Nucleus. Understanding the underlying formula is key to arriving at the correct answer below:
\(\text{Fe}^{56}\) is more stable because its binding energy per nucleon is higher than that of \(\text{U}^{235}\). However, the total binding energy of \(\text{U}^{235}\) is greater than that of \(\text{Fe}^{56}\) because it contains many more nucleons. Hence, Assertion is true but Reason is false.
