Explanation:
The buoyant force is extracted from the fluid's pressure on the surface. Because the pressure increases as the distance increases, the pressure at an object's bottom is always greater than the force at the top-hence the upward force of the net. Whether the object floats or falls, there is the buoyant force.
As the mass of the solid object becomes more and more immersed in the liquid, so does the upward ' buoyant force. ' The buoyant force acting on the solid reaches peak and remains constant afterwards when the object is completely immersed in the water.
Answer:
The buoyant force is maximum when the full body is submerged.
Explanation:
Archimedes principle says that if a body is either partially or fully submerged in a fluid, the fluid gives an opposing "force equal to weight" of an equal volume of it.
The buoyant force thus depends on the density of fluid in which can be dissolved. So, air gives less buoyant force than liquid. The buoyant force also depends on volume of fluid displaced. The maximum volume of fluid is displaced when a full amount of solid is displaced.
