If a feather, a rubber ball and a wooden ball are falling freely simultaneously from the same height in vacuum, then
Detailed Explanation:
In a vacuum, all objects fall with the same acceleration (g = 9.8 m/s²) regardless of mass or composition, as demonstrated by Galileo's principle. Without air resistance, a feather, rubber ball, and wooden ball experience identical downward acceleration.
Air resistance normally causes lighter objects like feathers to fall slower on Earth, but in vacuum conditions this factor is completely eliminated, making mass and material properties irrelevant to fall time.
Therefore, all three objects reach the ground simultaneously, making Option 4 the correct answer.
