In a vacuum, a five-rupee coin, a feather of a sparrow bird and a mango are dropped simultaneously from the same height. The time taken by them to reach the bottom is t1, t2 and t3 respectively. In this situation, we will observe that
A. t1 > t2 > t3
B. t1 > t3 > t2
C. t3 > t1 > t2
D. t1 = t2 = t3

D. t1 = t2 = t3
Correct option (d) t1 = t2 = t2
Explanation:
If the objects are dropped from the same height, they will reach the bottom simultaneously. Gravitational force is independent of the mass of the body. The acceleration due to gravity is same for all the objects. Also, there is no resistance offered by the air or any upward force, since the objects are dropped in vacuum.
Therefore, t1 = t2 = t3
