# What is the amount of buoyant force acting on a steel ball that displaces 3 ml of water in a graduated cylinder?

0.25 n

### Does the buoyant force on a submerged inflated balloon increase as it sinks?

No, it actually might decrease due to balloon being compressed by pressure. Floating objects are governed by Archimedes Principle which states that the weight of a floating object is equal to the water it displaces. A corollary of Archimedes Principle is that the buoyant force acting on an object is equal to the volume of water displaced. Therefore, when a balloon is compressed as it submerges it displaces less water and the buoyant force decreases…

### Can buoyant force be zero?

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…

### How could you determine your buoyant force acting on you when you are floating in water?

Use Archimedes' Principle: the buoyancy force of a submerged (or partially submerged) object is the weight of the volume of water that the object displaces. In other words, find the volume of the object that is under water, and multiply that by the density of water (1000 kg/cubic meter) and gravity (9.8 meter/sec/sec).

### What is the size of the buoyant force acting on an object?

The buoyant force is equal to the weight of the water displaced. Buoyant force = [density of water] x [volume displaced] x [gravity] Imagine you had a box of water that is itself under water. The forces would of course be balanced. This means that whatever the force of gravity would be on a box of water that size, that's what the buoyant force must be.

### What is the amount of buoyant force acting on a 85kgm 180cm tall person?

Up-thrust depends on the amount of volume of water the man displaces, therefore his shape, and not on his weight. He will sink until his weight and the volume of water displaced is the same and he would be floating. So the amount cant be calculated. Depending which is stronger, the weight of the person or the buoyancy, determines whether he sinks or floats. There will be more buoyant force with salt water than fresh…
