In what direction does the buoyant force on an object immersed in a liquid act?

Options

A. `Vrhog`
B. `(rhog)/V`
C. `rhogV^2`
D. `sqrt(rhogV)`

Answer

To determine the direction of the buoyant force on an object immersed in a liquid, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Buoyant Force**:
- Buoyant force is the upward force exerted by a fluid on an object that is submerged in it. This force is a result of the pressure difference between the top and bottom of the object.

2. **Pressure in a Fluid**:
- In a fluid, pressure increases with depth. The pressure at the bottom of the object is greater than the pressure at the top of the object because the fluid above the bottom surface exerts additional weight.

3. **Resultant Force**:
- The difference in pressure between the bottom and top surfaces of the object results in a net upward force. This upward force is what we call the buoyant force.

4. **Direction of the Buoyant Force**:
- Since the buoyant force arises from the pressure difference, it always acts in the opposite direction to the weight of the object. The weight of the object acts downwards due to gravity.

5. **Conclusion**:
- Therefore, the buoyant force on an object immersed in a liquid acts in the upward direction.

### Final Answer:
The buoyant force on an object immersed in a liquid acts in the upward direction.
