Choose the correct statement.

Options

A. Range of strong nuclear force is =`10^(-15)` m
B. Range of weak nuclear force is `= 10^(- 16)` m
C. Gravitational and electromagnetic force have infinite range
D. All of these

Answer

To solve the question "Choose the correct statement," we will analyze each statement regarding the ranges of the fundamental forces in physics.

### Step 1: Understand the Fundamental Forces
There are four fundamental forces in nature:
1. Strong Nuclear Force
2. Weak Nuclear Force
3. Electromagnetic Force
4. Gravitational Force

### Step 2: Analyze the Statements
1. **Statement 1**: The range of the strong nuclear force is \(10^{-15}\) meters.
- The strong nuclear force indeed has a very short range, typically around \(10^{-15}\) meters, which is the scale of atomic nuclei.

2. **Statement 2**: The range of the weak nuclear force is \(10^{-16}\) meters.
- The weak nuclear force also has a short range, and it is approximately \(10^{-16}\) meters, which is shorter than that of the strong nuclear force.

3. **Statement 3**: The gravitational and electromagnetic forces have an infinite range.
- Both gravitational and electromagnetic forces are long-range forces. They can act over infinite distances, although their strength diminishes with distance.

### Step 3: Conclusion
All three statements are true based on the established knowledge of fundamental forces:
- The strong nuclear force has a range of \(10^{-15}\) meters.
- The weak nuclear force has a range of \(10^{-16}\) meters.
- The gravitational and electromagnetic forces have an infinite range.

Thus, the correct answer is that all of these statements are true.

### Final Answer
All statements are correct.
