Question

You have a bag of cotton and an iron bar, each indicating a mass of 100 kg when measured on a weighing machine. In reality, one is heavier than other. Can you say which one is heavier and why?¿

Answer 1

Answer:

The heaviness of the bag can be given by density

$\large\frak\red{Densit {\sf{y}} = \frac{Mass}{Volume}}$

Mass of both cotton bag and iron bag is same. But the volume of cotton bag is more than the iron bag.

Hence density is inversely proportional to volume. The bag of iron will be heavier.

Answer 2

Answer:

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