Q: What is the magnitude of buoyancy force depends on?
  • A. The mass
  • B. The density
  • C. Temperature
  • D. Volume
Correct Answer: Option C - The property of a fluid, due to which it exerts an upward force on an object partially or completely immersed in that fluid, is called a buoyancy or buoyancy force. This force acts on the centeroid of volume of fluid displaced by object which is called centre of buoyancy. If an object floats in a liquid, the upward force exerted by the fluid or liquid on the object is equal to the weight of the liquid of fluid displaced by the object.
