What do you mean by buoyancy ? in points​

Answer 1

Answer:

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.

Answer 2

Answer:

Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/) or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. ... Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object.
