What is the principal cause of action of buoyant force on a body submerged partially or fully in fluid?

(a) Displacement of fluid due to submerged body

(b) Development of force due to dynamic action

(c) Internal shear forces mitigating external forces

(d) None of the mentioned

The question was asked during an internship interview.

This intriguing question originated from Bouyancy topic in chapter Buoyancy and Floatation of Fluid Mechanics

Best answer

The correct answer is (a) Displacement of fluid due to submerged body

The explanation: The principal cause of action of buoyant force on a body submerged partially or fully in fluid is the force equal in magnitude to the weight of the volume of displaced fluid.

In a U-tube mercury manometer, one end is exposed to the atmosphere and the other end is connected to a pressurized gas. The gauge pressure of the gas is found to be 40 kPa. Now, we change the manometric fluid to water. The height difference changes by: (ρmercury = 13600 kg/m^3, ρwater = 1000 kg/m^3).
