Which statement is incorrect for liquid pressure?

Options

A. Liquid pressure acts on the top of the container.
B. Liquid pressure acts on the sides of the container.
C. Liquid pressure acts on the bottom of the container.
D. Liquid pressure acts on containers of all sizes and shapes.

Answer

To determine which statement is incorrect regarding liquid pressure, we will analyze each statement provided in the question.

### Step-by-Step Solution:

1. **Understanding Liquid Pressure**:
- Liquid pressure is the pressure exerted by a liquid at a given depth due to the weight of the liquid above it. It acts in all directions and increases with depth.

2. **Analyzing Each Statement**:
- **Statement 1**: "Liquid pressure acts on the top of the container."
- This statement is incorrect. At the top of the liquid, the height (h) is zero, which means the pressure exerted by the liquid at that point is also zero. Therefore, there is no liquid pressure acting on the top of the container.

- **Statement 2**: "Liquid pressure acts on the sides of the container."
- This statement is correct. Liquid pressure does act on the sides of the container due to the weight of the liquid above.

- **Statement 3**: "Liquid pressure acts at the bottom of the container."
- This statement is also correct. The pressure at the bottom of the container is the maximum pressure experienced by the liquid due to the entire column of liquid above it.

- **Statement 4**: "Liquid pressure acts on the container of all sizes and shapes."
- This statement is correct as well. Liquid pressure acts irrespective of the shape or size of the container, as long as there is a height of liquid present.

3. **Conclusion**:
- The incorrect statement regarding liquid pressure is: **"Liquid pressure acts on the top of the container."**

### Summary of Incorrect Statement:
The incorrect statement is that liquid pressure acts on the top of the container, as there is no pressure exerted at that point due to the height being zero.
