Question

If an iron ball and a wooden ball of the same radius are released from a height h in vacuum, then time taken by both of them, to reach the ground will be : (A) zero (B) unequal (C) roughly equal (D) exactly equal

Since, the time of fall of both balls in vacuum do not depends on the mass of balls, hence, the time taken by both balls will be exactly equal.
