Question

What is the Obsersvable effects of buoyant force

Answer 1

Buoyancy is the upward forceexerted on an object when it is immersed, partially or fully, in a fluid - and strictly where the fluid is subjected to a gravitationalforce but is not in free fall - and its value is equal to the weight of the fluid displaced by the object.

Answer 2

byoyant force comes from the pressure exerted on the objects by the fluid.because the pressure exerted as the depth increases the pressure on the bottom of an objects is always larger than the force in the top. the buoyant is present whether a object sink or float .
1 Rational stability depends on the relative lines of action of force on the object.
2 the upward buoyancy force on object acts as the centre buoyancy.
3 Being the centroid of the displaced volume of fluid .
the weight force on the object act as through the centre of gravity
