Question

In a vacuum, a five-rupee coin, a feather of 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

Answer 1

Correct option is (d) t₁ = t₂ = t₃

As, we know that,

v = u + gt

t = v-u/g

where, v = 0, u and g are same in all the three conditions:

So, t₁ = t₂ = t₃
