State three characteristic properties of upthrust.

The upthrust has the following three characteristic properties:

1. Larger the volume of a body submerged in a fluid, greater is the upthrust.
2. For the same volume of a body inside a fluid, more the density of fluid, greater is the upthrust.
3. The upthrust acts on the body in upward direction at the centre of buoyancy i.e., the centre of gravity of the displaced fluid.
