Options

A. 1,2,3,4
B. 1,3,2,4
C. 4,3,2,1
D. 4,1,2,3

Explanation

To arrange the basic forces in increasing order of their relative strength, we first need to understand the relative strength of each force compared to the strongest force, which is the strong nuclear force. Here’s how we can approach the problem step by step:

### Step-by-Step Solution:

1. **Identify the Forces**: The forces we need to consider are:
- Gravitational force
- Electromagnetic force
- Weak nuclear force
- Strong nuclear force

2. **Determine Relative Strengths**: We need to know the relative strengths of these forces. The relative strengths compared to the strong nuclear force (which we can take as 1) are:
- Strong nuclear force: \(1\)
- Electromagnetic force: \(10^{-2}\)
- Weak nuclear force: \(10^{-30}\)
- Gravitational force: \(10^{-39}\)

3. **Arrange in Increasing Order**: Now, we will arrange these forces in increasing order of their relative strengths:
- Gravitational force: \(10^{-39}\) (weakest)
- Weak nuclear force: \(10^{-30}\)
- Electromagnetic force: \(10^{-2}\)
- Strong nuclear force: \(1\) (strongest)

4. **Final Order**: Based on the relative strengths, the increasing order is:
- Gravitational force (1)
- Weak nuclear force (3)
- Electromagnetic force (2)
- Strong nuclear force (4)

5. **Select the Correct Option**: From the options given:
- Option 1: 1, 2, 3, 4
- Option 2: 1, 3, 2, 4
- Option 3: 4, 3, 2, 1
- Option 4: 4, 1, 2, 3

The correct option that matches our order (1, 3, 2, 4) is **Option 2**.

### Summary of the Solution:
The forces arranged in increasing order of relative strength are:
1. Gravitational force
2. Weak nuclear force
3. Electromagnetic force
4. Strong nuclear force

Thus, the correct answer is **Option 2: 1, 3, 2, 4**.
