The distance between nucleons in atomic nucleus is the order of (1 Fermi `= 13^(-13) cm`)

Options

A. 2 Fermi
B. 25 Fermi
C. 100 Fermi
D. 40 Fermi

Answer

To solve the question regarding the distance between nucleons in an atomic nucleus, we will follow these steps:

### Step 1: Understand the Definition of Fermi
1 Fermi (1 fm) is defined as \( 10^{-13} \) cm. This is a unit of length commonly used in nuclear physics to describe distances on the scale of atomic nuclei.

### Step 2: Determine the Typical Distance Between Nucleons
The typical distance between nucleons (protons and neutrons) in an atomic nucleus is approximately 1 to 2 Fermi. For this problem, we will use the value of 2 Fermi as a representative distance.

### Step 3: Convert Fermi to Centimeters
Since 1 Fermi is \( 10^{-13} \) cm, we can express 2 Fermi in centimeters:
\[ 2 \text{ Fermi} = 2 \times 10^{-13} \text{ cm} \]

### Step 4: Conclusion
Thus, the distance between nucleons in an atomic nucleus is in the order of \( 2 \times 10^{-13} \text{ cm} \).

### Final Answer
The distance between nucleons in an atomic nucleus is approximately 2 Fermi.
