Answer 2

When an object is submerged in a fluid, such as a liquid, there are two main forces acting on it: gravity and buoyancy. The force of gravity pulls the object downward, while the force of buoyancy, also known as the Archimedes' principle, pushes the object upward. The relationship between these forces depends on the density of the object and the density of the fluid.

Condition 1: Density of the object is equal to the density of the fluid

If the density of the object is equal to the density of the fluid, then the force of gravity and the force of buoyancy will be equal. In this case, the object will float in the fluid, neither sinking nor rising. This is known as neutral buoyancy.

Condition 2: Density of the object is less than the density of the fluid

If the density of the object is less than the density of the fluid, then the force of gravity will be greater than the force of buoyancy. As a result, the object will sink in the fluid. The difference between the force of gravity and the force of buoyancy determines the acceleration of the object as it sinks.

Condition 3: Density of the object is greater than the density of the fluid

If the density of the object is greater than the density of the fluid, then the force of gravity will be less than the force of buoyancy. In this case, the object will float on the surface of the fluid or rise to the top. The difference between the force of buoyancy and the force of gravity determines the acceleration of the object as it rises.

It's important to note that the density of an object is defined as its mass divided by its volume, while the density of a fluid is the mass of the fluid divided by its volume. The density of an object and the density of a fluid can be compared to determine the behavior of the object when submerged.
