When a body moves in a circular path, outward force is called a ......

Options

A. Pseudo force
B. Centrifugal force
C. Centripetal force
D. Reaction force

Explanation

To solve the question "When a body moves in a circular path, outward force is called a ......", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Circular Motion**:
- When an object moves in a circular path, it is constantly changing direction. This change in direction requires a force.

2. **Identifying the Inward Force**:
- The force that acts towards the center of the circular path is known as the centripetal force. This force is responsible for keeping the object in circular motion.

3. **Considering the Outward Force**:
- While the centripetal force acts inward, there is a perception of an outward force when an object is in circular motion. This perceived force is what we refer to as the outward force.

4. **Naming the Outward Force**:
- The outward force experienced by an object moving in a circular path is called centrifugal force. It is important to note that centrifugal force is considered a pseudo force because it is not an actual force acting on the object but rather a result of inertia.

5. **Conclusion**:
- Therefore, the correct answer to the question is that when a body moves in a circular path, the outward force is called **centrifugal force**.

### Final Answer:
When a body moves in a circular path, outward force is called **centrifugal force**.
