In CGS system, the unit of force is

Options

A. newton
B. pascal
C. dyne
D. metre

Explanation

To solve the question "In CGS system, the unit of force is", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the CGS System**:
- The CGS system stands for Centimeter-Gram-Second. It is a metric system of units where:
- Length is measured in centimeters (cm)
- Mass is measured in grams (g)
- Time is measured in seconds (s)

2. **Identify the Unit of Force**:
- In physics, force is defined as mass times acceleration (F = m × a).
- To determine the unit of force in the CGS system, we need to look at the units for mass and acceleration.

3. **Calculate the Unit of Force**:
- In the CGS system:
- Mass (m) is in grams (g)
- Acceleration (a) is in centimeters per second squared (cm/s²)
- Therefore, the unit of force in CGS can be derived as:
- Force (F) = Mass (g) × Acceleration (cm/s²)
- This gives us the unit of force as gram-centimeter per second squared (g·cm/s²).

4. **Convert to Standard Unit**:
- The unit of force in CGS is specifically called a "Dyne".
- Thus, 1 Dyne = 1 g·cm/s².

5. **Conclusion**:
- The correct answer to the question is that in the CGS system, the unit of force is **Dyne**.

### Final Answer:
**In the CGS system, the unit of force is Dyne.**
