On which of the following factors the magnitude of the buoyant force acting on a body in a given fluid depends?

The correct answer is the Density of the fluid and the volume of the body immersed in it.

Key Points

• The buoyant force depends on the volume of the liquid displaced. The buoyant force depends on the mass of the object, the weight of the object, and its density.
• The buoyant force depends directly upon:
  • The volume of the fluid displaced.
  • The density of the fluid in which the body is immersed.
  • Acceleration due to gravity at the place.

Important Points

• The three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy.
  • Positive buoyancy is when the immersed object is lighter than the fluid displaced and this is the reason why the object floats.
  • Negative buoyancy is when the immersed object is denser than the fluid displaced which results in the sinking of the object.
  • Neutral buoyancy takes place when the weight of an immersed object is equal to the fluid displaced.
