Two nuclei have mass numbers in the ratio 27 : 125. What is the ratio of their nuclear radii ?

Explanation

To find the ratio of the nuclear radii of two nuclei with mass numbers in the ratio of 27:125, we can use the formula for nuclear radius.

### Step-by-Step Solution:

1. **Understand the relationship between nuclear radius and mass number**:
The nuclear radius \( R \) is given by the formula:
\[
R \propto A^{1/3}
