Nucleus: Practice Problem & Solution

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:

The radius of an atom is of the order of $10^{-10} m$, and the radius of a nucleus is of the order of $10^{-15} m$. The ratio of their volumes is proportional to the cube of their radii ratio: $(10^{-10} / 10^{-15})^3 = (10^5)^3 = 10^{15}$.
