Answer:
The density of cotton bag is less than that of the iron bar, so the volume of cotton bag is more compared to iron bar. So the cotton bag experience more up thrust due to the presence of air. Therefore in the presence of air the true weight of cotton bag is more compared to the true weight of iron bar.
