Hint: In this question we have been asked to define buoyant force. We have also been asked to determine two factors on which the buoyant force depends. Therefore, to answer this question, we shall first describe the buoyant force. We shall study the causes of buoyant force. This shall help us in naming the two important factors on which the buoyant force depends. We know that buoyancy is the force that causes objects to float in the liquid.
Complete step-by-step solution
Buoyancy also is known as upthrust is an upward force that opposes the weight of the body partially or fully immersed in the fluid. The buoyant force is applied to the object by the fluid in which the object is immersed. We know that the pressure of a fluid in a column increases as the depth of the column increases. This is due to the increase in the weight of fluid due to an increase in depth. Therefore, if an object is immersed in the fluid, the top surface of the object will be at a lower pressure than the bottom surface of the object. This pressure difference will result in a net upward force. This force is known as the buoyant force.
