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?

Question

 1) 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.

2)  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.

 3) 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.

 4) 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.

I think it's 1 because buoyant force depends on the amount of water displaced and a sinking object displaces more water.

Answer 1

Hi ? Are you saying hi to see if I am still "there"?

Answer 2

read the 1st sentence ... then try again

Answer 3

I feel like the answer is 2 or 3? Although it does say that both are submerged under water which could mean the answer is 2 they both have the same buoyant force acting upon them.

Answer 4

I think its answer 4
