Two nuclei have mass number in the ratio 1:8. 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 1:8, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Given Information**:
We are given that the mass numbers of two nuclei are in the ratio \( A_1 : A_2 = 1 : 8 \). This can be expressed as:
\[
\frac{A_1}{A_2} = \frac{1}{8}
