When ______ acts between two charged objects, it can be both attractive and repulsive.

Options

A. electrostatic force
B. muscular force
C. gravitational force
D. force of gravity

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a force that can act between two charged objects and can be both attractive and repulsive.

2. **Identifying the Options**: The options provided are:
- Force
- Electrostatic force
- Muscular force
- Gravitational force
- Force of gravity

3. **Analyzing the Nature of Forces**:
- **Muscular Force**: This is not applicable as it relates to the force exerted by muscles, not charged objects.
- **Gravitational Force**: This force is always attractive and does not apply to charged objects in the context of attraction and repulsion.
- **Force**: This is a general term and does not specify the type of force acting between charged objects.

4. **Focusing on Electrostatic Force**:
- The electrostatic force acts between charged objects.
- It can be attractive if the charges are of opposite signs (positive and negative).
- It can be repulsive if the charges are of the same sign (both positive or both negative).

5. **Conclusion**: The force that acts between two charged objects and can be both attractive and repulsive is the **electrostatic force**.

**Final Answer**: When **electrostatic force** acts between two charged objects, it can be both attractive and repulsive.
