Complete the following sentences:
An empty tin container with its mouth closed has an average denstiy equal to that of a liquid. The container is taken 2 m below the surface of that liquid and is left there. Then the container will…...…….

Answer

To solve the question, we need to analyze the situation described and apply the principles of buoyancy and density.

### Step-by-Step Solution:

1. **Understanding the Situation**:
- We have an empty tin container with its mouth closed.
- The average density of the container is equal to that of the liquid (water).

2. **Position of the Container**:
- The container is taken 2 meters below the surface of the liquid and is left there.

3. **Density Comparison**:
- Since the average density of the container is equal to the density of the liquid, we can infer that the forces acting on the container will be balanced.
- The buoyant force acting on the container (which is equal to the weight of the liquid displaced by the container) will be equal to the weight of the container.

4. **Conclusion**:
- Because the buoyant force equals the weight of the container, the container will neither sink nor float.
- Therefore, the container will remain at the same position at a depth of 2 meters below the surface of the liquid.

5. **Final Sentence Completion**:
- The complete sentence is: "Then the container will remain at the same position at a depth of 2 meters below the surface of the liquid."
