In what direction and at what point does the buoyant force on a body due to a liquid, act ?
The buoyant force acts in the vertically upward direction, at the centre of buoyancy (which is the centre of gravity of the displaced fluid).
In what direction does the buoyant force on an object immersed in a liquid act?
A body of mass 10 kg and volume 0.5 m3 is placed in a liquid. What is the density of the liquid when buoyant force is equal to weight of the body? (Take acceleration due to gravity = 10 m/s2)
