If the size of a nucleus `(~~10^(-15)m)` is scaled up to the tip of a sharp pin `(~~ 10^(-5)m),` what roughly is the size of an atom?

Explanation

To solve the problem, we need to determine the apparent size of an atom when the size of a nucleus is scaled up to the size of the tip of a sharp pin. Here are the steps to arrive at the solution:

### Step 1: Identify the actual size of the nucleus
The actual size of the nucleus is given as:
\[ \text{Actual size of nucleus} = 10^{-15} \text{ m} \]
