Question

Define Bouyant force

class 9 NCERT ​

Answer 1

Definition of buoyant force. : the upward force exerted by any fluid upon a body placed in it — compare archimedes' principle.

Answer 2

In physics, 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.
