2: Both objects will hit at the same time as there is no air resistance on both objects.

2- Both of them at the same time because air is absent

Q2: The both of them will touch the ground at the same time. The acceleration due to gravity will be same on both objects and there is on air resistance.

Q2: Both will land on the same time because there is no air resistance.

2)both objects will hit at the same time as there is no air resistance on both objects.

2.Both objects will hit at the same time because there no air resistance.
