Height of second object from the ground after 2s then h₂ = 100m – 20m = 80m Now, difference in the height after 2s = h₁ – h₂= 130 – 80= 50 m
The difference in hights of the objects will remain same with time as both the objects have been dropped from rest and are falling with same acceleration i.e., (acceleration due to gravity).
