In summary, the conversation is about a question asking for the buoyant force acting on an object that weighs 6.4 N when fully immersed in water. However, the question does not provide enough information and the person has not been able to find a solution using the given formula. They suggest understanding the principles behind the problem and mention Archimedes's principle. The question is then verified as being incomplete.

Hey,
The question is:
"AN object weighs 6.4 N when fully immersed in water. Find the buoyant force acting on it."
I have not even come near to the solution because it doesn't fit in the formula.

thanks in advance.

As stated, there is not enough information given to answer the question. Please post the problem exactly--word for word--as it was given to you.

Also, try to understand the principles instead of just looking for a formula to use. Read up on Archimedes's principle.

that's the exact word to word question and i think its true-the question is incomplete
i'll verify, thanks otherwise
 

FAQ: Solving a Buoyancy Question - 6.4 N Weight in Water

How do you calculate the buoyant force on an object?

The buoyant force on an object can be calculated by multiplying the density of the fluid by the volume of the fluid displaced by the object and the acceleration due to gravity (Fb = ρVg).

What is the formula for calculating the weight of an object in water?

The weight of an object in water can be calculated by subtracting the buoyant force from the weight of the object (Ww = W - Fb).

How do you determine if an object will float or sink in water?

An object will float if its weight is less than the buoyant force acting on it, and it will sink if its weight is greater than the buoyant force.

Does the shape or size of an object affect its buoyancy?

Yes, the shape and size of an object can affect its buoyancy. Objects with a larger surface area will experience more buoyant force, while objects with a denser and more compact shape will experience less buoyant force.

How does the density of an object affect its buoyancy?

The density of an object plays a crucial role in its buoyancy. Objects with a lower density than water will float, while objects with a higher density will sink. The density of an object is determined by its mass and volume.
