The buoyant force on a submerged object is the weight of the water it displaces ... the water it pushes out of the way. That amount is simply the volume of the submerged object. So the more volume is submerged, the greater will be the buoyant force acting on it.
Since Aluminum is less-dense than lead, the same 10kg of Aluminum needs a bigger container to hold it than 10kg of lead needs. The aluminum needs more volume to hold the same mass.
The aluminum displaces more water. So the buoyant force acting on the aluminum is greater than the buoyant force acting on the lead. (B) .
I'm guessing this is a big part of the reason why fishing sinkers are not made of aluminum.
Aluminum has greater buoyant force than lead.
To determine the answer, we need to know about the buoyant force.
What is buoyant force?
- Buoyant force is experienced by an object when moving in water (or any liquid substance) along the opposite direction of motion.
- It is a frictional force in water.
- This force is exerted by water.
- The magnitude of the force is given as the weight of water displaced corresponding to that volume at which the sinked object displaces the water.
- I.e. buoyant force=density of water × volume × g. Where volume= volume of the object sink in the water (it is also the volume of water displaced by the object.)
Which has more buoyant force between aluminum and lead?
- According to question, the masses of aluminum and lead are same (10Kg).
- As masses are same, so their volume is inversely proportional to the density.
- Since, the aluminum has less density than lead, it has more volume than lead.
- We know that the buoyant force depends on the volume of sinked object. So as the aluminum has more volume than lead, it has more buoyant force.
Thus, we can conclude that aluminum has greater buoyant force than lead.
