Answer 1

Answer:

They will weight the same. Density of iron is more, gravitational pull on iron is more. But the weight will arrives at equilibrium by placing more mass of cotton.

Explanation:

When I buy vegetable, 1kg of iron is placed on one side of the weight balance. Vegetable on the other side. I will get the same weight of vegetable as the iron measure.

The bag of cotton is heavier than the bar of iron. The cotton bag has a larger air thrust than the iron bar. The weighing machine therefore indicates a smaller cotton bag weight than its actual weight.
