Question

A feather and marble were released from the second floor of a building. The marble hit the ground first and the feather later. The same feather and marble were released from an evacuated long glass tube. This time they hit the bottom of the tube at the same time. Which of the following is the reason for this?

  1. The feather was subjected to a greater air resistance outside the evacuated tube.
  2. The feather was subjected to a smaller air resistance inside the evacuated tube.
  3. The marble was subjected to greater air resistance outside the evacuated tube.
  4. The marble was subjected to a smaller air resistance inside the evacuated tube.[RS1] 

    @Production team, please resolve the alignment of the numbers with their respective options as it cannot be done via online MS-WORD.  [RS1]

hintHint:

The feather was subjected to a greater air resistance outside the evacuated tube.

The correct answer is: The feather was subjected to a greater air resistance outside the evacuated tube.
