Which one of the following pattern of electric line of force can't possible:

Options

A.
B.
C.
D.

Explanation

To determine which pattern of electric lines of force is not possible, we need to analyze each option provided in the question. Here’s a step-by-step solution:

### Step 1: Understand Electric Field Lines
Electric field lines represent the direction and strength of an electric field. They have specific characteristics:
- They originate from positive charges and terminate at negative charges.
- They never cross each other.
- They can diverge or converge but cannot form closed loops.

### Step 2: Analyze Each Pattern
1. **Straight Electric Field Lines**: This pattern is possible. It represents a uniform electric field, which can occur between two parallel plates with equal and opposite charges.

2. **Radial Electric Field Lines**: This pattern is also possible. It represents the electric field around a point charge, where lines radiate outward from a positive charge or inward toward a negative charge.

3. **Closed Loop Electric Field Lines**: This pattern is not possible. Electric field lines cannot form closed loops because they must start at a positive charge and end at a negative charge. If they formed a closed loop, it would imply that there is no net charge to create the field.

4. **Diverging Electric Field Lines**: This pattern is possible. It represents the electric field around multiple positive charges, where the lines spread out from each charge.

### Step 3: Conclusion
From the analysis, the pattern that is not possible is the one with closed loop electric field lines.

### Final Answer
The pattern of electric lines of force that cannot be possible is the closed loop electric field lines.
