Buoyancy force is the weight of displaced fluid. So the buoyant force given by a liquid is directly proportional to the density of that liquid. Buoyant force = density of the liquid * volume of the object inside the liquid * gravitational constant g. Hope this answers your question. read more
The greater the density of the fluid, greater is the buoyancy. For example, when a piece of wood is pushed into different fluids, different forces have to be applied to do so. the denser the fluid, more is the force required to push the body into it. read more
Best Answer: higher density means the weight of water displaced is less than the weight of object so buoyancy force will not be able to make the object float and it will sink , so less buoyancy for heavier objects. read more
