Kindly tell me, what happens to an object floating in water otherwise, if it is falling freely under gravity? Explain the reason for the effect.

Hi "narengo iit"

Can you please explain the scenario a little more.

Any object falling freely under gravity will experience a downward acceleration of g = 9.8 m/s^{2

It will also experience an upward resistive force due to air.}

If an object is floating in some fluid say water, then its portion will be immersed in water and the portion immersed will be such that it displaces liquid of equal volume so as to provide buoyant force to the object and consequently the obect floats.

Now, we assume the same under free fall

Under free fall of an object or system there is a phenomenon of WEIGHTLESSNESS. Thus, the body which was floating will continue to float and its none of the fration/portion will be immersed in the water and there will not be any buoyancy.
