And if this ratio is equal to one, then that means if the density of those two particles is if the density of the particle is the same at the density of the fluid, that fluid and that particle will not move with respect to one another. So if this ratio is equal to one, that particle will not move inside the fluid because their densities are equal. So remember, from physics we know that an object will float or an object will sink. And that depends on the density of that object with respect to the density of that fluid. Now, if the product of V Bard row is greater than one, then that means the fluid has a higher density than that particle. And so that particle will float on top of that fluid.
