Detailed Solution

Buoyant force is defined as the upward force exerted by a fluid on a body immersed on it.
According to the Archimedes principle, if an object is immersed in a fluid, it experiences an apparent loss of weight equal to the weight of the fluid displaced by the immersed object. This is because the buoyant force, which acts in the upward direction opposite to the direction of the object's weight, causes the apparent loss in weight.
The definition of buoyancy refers to whether something can float in liquid or gas. The power of water or other fluids to keep some things floating is buoyancy. An Example of buoyancy is when a boat floats in water, or a cork floats on water.
