Question

Two crates are submerged under water. The crates are identical in size, but Crate A is filled with iron and Crate B has only air inside. Which crate has a greater buoyant force acting on it?

Responses

Crate A has a greater buoyant force acting on it because it is filled with iron, making it heavier. Buoyant force depends on the weight of the object.

There is no way of knowing which object has a greater buoyant force acting on it until we can determine if they float. If both objects float, they have the same amount of buoyant force acting on them.

Both crates have the same amount of buoyant force acting on them because they are the same size and displace the same amount of water.

Crate B has a greater buoyant force acting on it because it is filled with air, so it will float. The object that floats will always have a greater buoyant force acting on it.

They have the same upward force of Buoyancy!
rho g V !!!!!!

Yes, that is correct. The upward force of buoyancy on an object is given by the equation rho x g x V, where rho is the density of the fluid, g is the acceleration due to gravity, and V is the volume of the displaced fluid. In this case, both crates have the same volume and are submerged in the same fluid, so they experience the same upward force of buoyancy.
