**Incorrect statement: The spring force always pushes a body**
The spring force can either push or pull a body, depending on the direction in which the spring is stretched or compressed. This statement is incorrect because it assumes that the spring force always acts in one specific direction.
**Explanation:**
1. **The weight of a body always acts towards the centre of the Earth:**
- This statement is correct. The weight of a body is the force exerted on it due to gravity, and it always acts towards the center of the Earth. This is because gravity pulls objects towards the center of the Earth.
2. **Frictional force always acts parallel to the surface of contact:**
- This statement is also correct. Friction is a force that opposes the relative motion or tendency of motion between two surfaces in contact. The direction of frictional force is always parallel to the surface of contact and opposite to the direction of motion or motion tendency.
3. **The spring force always pushes a body:**
- This statement is incorrect. The spring force can either push or pull a body, depending on the direction in which the spring is stretched or compressed. When a spring is stretched or compressed, it exerts a force that tries to restore it to its equilibrium or natural position. If the spring is stretched, it exerts a force in the opposite direction, trying to pull the objects towards each other. If the spring is compressed, it exerts a force in the opposite direction, trying to push the objects apart.
4. **The tension of a string always pulls a body:**
- This statement is correct. The tension in a string or rope is a force that is transmitted through the string when it is pulled tight. The tension force always acts along the length of the string and pulls the body in the direction of the applied force.
In summary, the incorrect statement is that the spring force always pushes a body. The spring force can either push or pull a body, depending on the direction in which the spring is stretched or compressed.
