Name the factors on which the buoyant force depends?

The buoyant force depends on the volume of the object submerged, the density of the fluid, and the acceleration due to gravity. Buoyant force is the upward force exerted by a fluid (like water or air) that opposes the weight of an object immersed in it. 

According to Archimedes' Principle, the magnitude of the buoyant force is equal to the weight of the fluid displaced by the object.

The key factors are:

• Volume of the object submerged: More volume means more fluid is displaced, increasing the buoyant force.
• Density of the fluid: Heavier fluids like salt water exert a greater buoyant force than lighter fluids like fresh water or air.
• Gravitational acceleration (g): On planets with higher gravity, the buoyant force will also be stronger.

These three factors together determine how much upward force an object experiences in a fluid. An object will float if the buoyant force is greater than its weight.
