Question

what is upthrust force​

Answer 1

Explanation:

Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column.

Answer 2

When a body is partially or wholly immersed in a liquid, an upward force acts on it. This upward force is known as upthrust or buoyant force. The upward force exerted on a body by the fluid in which it is submerged, is called the upthrust or buoyant force.
