A stone and feather are thrown from a tower both the objects should reach the ground at the same time but it does not. Why?

Dear student,

Two  object of any mass will reach to ground at same time if dropped from same height. But the statement is true only in vacuum.
But in normal condition when we drop some thing, we have to take care of the air resistance also.
Since the density of feather is much less than the stone, the air resistance on the feather is much more than pin. So feather will take more time than pin to come down to the ground but if you do the experiment in vacuum, they will take same time.
