on the object wholly or partially immersed in a

it is called buoyancy.

in a fluid is called buoyancy force.

Answer 2

Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/), or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.
