Calculate the buoyant force acting on an object immersed in water, if the object displaces 4 kg of water.

Explanation

To calculate the buoyant force acting on an object immersed in water, we can use the principle of buoyancy, which states that the buoyant force is equal to the weight of the fluid displaced by the object. Here’s how to solve the problem step by step:

### Step-by-Step Solution:

1. **Identify the Mass of Water Displaced**:
The problem states that the object displaces 4 kg of water.

2. **Calculate the Weight of the Displaced Water**:
