Best Answer

Yes, it can if you fit density of the material to the density of the surrounding media the force is zero.

ANS2:The only ways that the buoyant force could be zero is when the object is not in contact with a fluid* such as may be encountered in the vacuum of outer space or when there is no gravitational force pulling the fluid downward.

Remember, that the object does not need to be floating for a buoyant force to be acting on it. A brick weighs slightly less because it displaces its volume of air and that air that was displaced is pushing up on the brick.

*"Fluid" includes gases and liquids.

What is the buoyant force that acts on a 100 ton ship?

Since the ship's vertical acceleration is zero, the net vertical force on it must zero,and the buoyant force must therefore be 100 tons.


What is the buoyant force that acts on a 100 ton floating ship?

Since the ship's vertical acceleration is zero, the net vertical force on it must zero, and the buoyant force must therefore be 100 tons.


The buoyant force on an object is least when the object is?

The buoyant force is zero when the object is just touching the liquid. As the object displaces more volume, the buoyant force increases until the object is completely submerged. Once the object is submerged, it doesn't matter how deep it is, the buoyant force remains constant.


What is the buoyant force acting on a 1000 pound floating in water?

If it's floating, then the buoyant force on it is exactly equal to its weight. (That makes the vector sum of the vertical forces zero, which is why the object is not accelerating vertically.)


An object that weighs 340 N floats on a lake what is the weight of the displaced water?

buoyant force acts on the object from its bottom and push it outside..the magnitude of the buoyant force acting on the object will b equal to the weight of displaced water..


What is the relationship between buoyant force and gravity?

buoyant force is always or equal to the force exerted by gravity. that's why an object floats.


Is the buoyant force of a metal equal to the buoyant force of a wood that has the same mass?

Buoyant force is based upon the mass of the water displaced. Therefore, two objects will have the same buoyant force if they have the some volumes.


What is an buoyant force?

A buoyant force equals the weight of the fluid being displaced


What is the relationship of buoyant force and density of liquid?

Buoyant force is directly proportional to the density of the liquid. as the density of the liquid increases, the Buoyant force increases.


If the apparent weight of an object can be found by subtracting the buoyant force from the weight of the object what is the apparent weight of the floating object?

Zero.


What happens if the buoyant force decreases?

As buoyant force decreases then the body starts sinking down.


What are the factors of buoyant force?

The buoyant force depends on the volume of liquid displaced and the density of the liquid.
