Dear mayank


Dear let force exert by air is F on both the bodies


do retardation = (F+mg)/m = g + F/m


clearly retardation on lighter body will  be more .so it will reach less hight as compair to heavier body.

NO they won't


as far as gravitation's acc is considered they would have reached same height


now if these bodies experiences equal force


there different retarding acc of the air


M1 X A1 = M2 X A2


M1 NOT EQUAL TO M2


THEREFORE A1 NOT EQUAL TO A2


HENCE DIFFERENT HEIGHT THEY WILL REACH

they wont reach same height.they hav 2 diff masses{say M and m}whose weight acts downwards i.e., Mgsinθ and mgsinθ.therefore whichever has more mass reaches less height.
