to sum things up, we have no gravity.
According to the familiar principle of the Greek mathematician Archimedes the buoyant force is equal to the weight of the liquid that is displaced by the object. Since there is no weight, there is no buoyancy.
If there is a no-gravity environment in the elevator the perosn standing there would have 0 pressure on the feet. Therefore, there will be no air pressure or concentrations, as there are in the atmosphere.
Therefore, the balloon will stay in the middle.
Concluded for now................. now...........
or.........We excluded the point that the elevator falls faster than air. We shall forget gallileo because we are talking about different state mediums. So will there be air compression spots or will there be equal pressure distribution throughout the elevator. since there is no other force exerted on the balloon i think it will act as the air translates position. But the question remains.
I am guessing "Wind" is referred to the vertical translation of air particles inside the elevator creating different concentrations. So when the air particles move to the top of the elevator, they will cary the balloon with them, based on air resistance. And then if the acceleration remains uniform, it may move down. The acceleration has to be uniform for the constant upward force to be applied on the air. The force is also exerted on the balloon.
I am right or am i wrong?
