Question:
If \( M \) is the mass of nucleus and \( A \) its atomic mass, then the packing fraction is:
If \( M \) is the mass of nucleus and \( A \) its atomic mass, then the packing fraction is:
Show Hint
Packing fraction measures the deviation of nuclear mass from integer atomic mass.
Updated On: Mar 26, 2025
- \( \frac{M - A}{M + A} \)
- \( \frac{M - A}{M} \)
- \( \frac{M - A}{A} \)
- \( \frac{M + A}{M - A} \)
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Packing fraction is given by:
\[ \frac{M - A}{A} \] where \( M \) is the actual mass of the nucleus, and \( A \) is its atomic mass.
\[ \frac{M - A}{A} \] where \( M \) is the actual mass of the nucleus, and \( A \) is its atomic mass.
