Answer:
- equal to the weight of the fluid that the body displaces
Explanation:
Archimides' principle states the definition of buoyant force.
These are the imporant features of the buoyant force that you need to know:
- Except for the very special vacuum condition, every body is immersed in a fluid.
- The body is subject, at least, to two forces, its weight and the buoyant force.
- The weight is the result of the gravitational attraction exerted by the planet, and is equal to the mass of the object by the gravitational acceleration (approximately 9.8 m/s² on Earth). It is directed vertically downward.
- The buoyant force is the vertical upward force that the fluid exerts on the object and is equal to the weight of the volume of fluid displaced by the object.
- The volume of fluid that the body displaces is equal to the immersed volume of the body.
