A 4.5-newton object is placed in a tank of water. If the water exerts a force of 4.0 newtons on the object, will the object sink or float?

If W > fa = sink Else if W < fa = float
W = 4,5 N f = 4 N W > fa
And we know the object will sink

The object will continue to sink until it reaches the bottom of the tank .
What is buoyant force?
The buoyant force is the upward force exerted on an object when it is immersed or partially **immersed **in a fluid, such as water or air. It is also known as Archimedes' principle, named after the ancient Greek mathematician Archimedes who discovered this principle.
The **buoyant **force arises due to the difference in pressure between the top and bottom of the object immersed in the fluid. The pressure at the bottom of the object is greater than the pressure at the top, and this pressure difference generates an upward force on the object. The buoyant force is equal to the weight of the displaced fluid, and it acts in the opposite direction to the weight of the object.
If the** buoyant **force acting on an object is greater than the weight of the object, the object will float. If the buoyant force is less than the weight of the object, the object will sink. And if the buoyant force is exactly equal to the weight of the object, the object will remain suspended at the same level in the fluid, neither sinking nor floating.
Here in this question,
To determine whether the object will sink or float , we need to compare the buoyant force acting on the object to the weight of the object.
The** buoyant force** is equal to the weight of the water displaced by the object, and it acts in the opposite direction to the weight of the object.
In this case, if the water exerts a force of 4.0 newtons on the object, that means the buoyant force acting on the object is 4.0 newtons.
Therefore, if the weight of the object is 4.5 newtons, and the buoyant force is only 4.0 newtons, the object will sink . This is because the weight of the object is greater than the buoyant force acting on it, and the object will continue to sink until it reaches the bottom of the tank.

The 4.5-newton object will sink because its weight is greater than the buoyant force of 4.0 newtons exerted by the water. Since the weight (4.5 N) exceeds the buoyant force (4.0 N), the object cannot float. Therefore, it will continue to sink until it reaches the bottom of the tank.
