Concept:
Here, we will first learn the fundamentals of the Archimedes principle before learning some of its restrictions. Other physical concepts like weight, gravity, and buoyant force are brought into focus by Archimedes' principle.
According to the Archimedes principle, a buoyant force equivalent in strength to the force of gravity acting on the displaced fluid acts on a submerged item. The law of buoyancy is another name for it.
The weight of the displaced fluid is equal to the weight of the object in the fluid minus the weight of the object in the vacuum.
The volume of the displaced fluid is directly inversely related to its weight (if the surrounding fluid is of uniform density).
In terms of magnitude and direction, the buoyant force acting on a body floating in a liquid or gas is opposite to that of the object's weight. Consequently, the item does not ascend or fall in this condition.
Hence, the correct option is 1.
