Rahul is pushing a heavy sofa in the north-east direction. In which direction would frictional force act on the sofa?

Options

A. North-east
B. South-east
C. North-west
D. South-west

Answer

To determine the direction of the frictional force acting on the sofa that Rahul is pushing in the north-east direction, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Direction of Motion**:
- Rahul is pushing the sofa in the north-east direction. This means the sofa is moving towards the area that is between the north and east.

2. **Understand the Concept of Friction**:
- Frictional force always acts in the opposite direction to the direction of motion. This is a fundamental principle of physics.

3. **Determine the Opposite Direction**:
- Since the sofa is moving in the north-east direction, we need to find the direction that is opposite to this. The opposite direction to north-east can be determined by considering the compass directions.

4. **Identify the Opposite Direction**:
- The opposite of north-east is south-west. This is because if you visualize a compass, moving north-east means you are moving diagonally between north and east, and the opposite diagonal would be south-west.

5. **Conclusion**:
- Therefore, the frictional force acting on the sofa will be in the south-west direction.

### Final Answer:
The direction of the frictional force acting on the sofa is **south-west**.
