Electric lines of force about negative point charge are

Options

A. circular ,anticlockwise
B. circular ,clockwise
C. radial ,inward
D. radial , outward

Answer

To determine the nature of electric lines of force around a negative point charge, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electric Lines of Force**: Electric lines of force represent the direction of the electric field created by a charge. The lines indicate the path a positive test charge would take if placed in the field.

2. **Identifying the Charge Type**: In this case, we are dealing with a negative point charge. The sign of the charge affects the direction of the electric field lines.

3. **Direction of Electric Field Lines**: For a positive charge, electric field lines radiate outward, indicating that a positive test charge would be repelled. Conversely, for a negative charge, electric field lines point inward, indicating that a positive test charge would be attracted toward the negative charge.

4. **Radial Nature of the Field**: The electric field around a point charge is radial. This means that the lines of force extend directly away from or toward the charge in all directions, forming a pattern that resembles lines radiating from a central point.

5. **Conclusion**: Since we have established that the electric field lines for a negative point charge point inward and are radial, the correct answer is that the electric lines of force about a negative point charge are "Radial and inward."

### Final Answer:
The correct option is **3. Radial and inward**.
