Question

Let the binding energy per nucleon of nucleus be denoted by \( E_{bn} \) and radius of the nucleus by \( r \). If mass numbers of nuclei A and B are 64 and 125 respectively, then

• A. \( r_A < r_B \)
• B. \( r_A > r_B \)
• C. \( E_{bnA} > E_{bnB} \)
• D. \( E_{bnA} < E_{bnB} \)

Hint:

Nuclear trends: \begin{itemize} \item Radius \( \propto A^{1/3} \). \item Binding energy per nucleon peaks near Fe. \end{itemize}

Answer 1

The Correct Option is A
