Question

Three different liquids are taken in three identical measuring cylinders. If 3 identical stones each of volume $200{\text{cm}}^3$ are dropped into each of the cylinders, find the rise in liquid level in each of the measuring cylinders.

Liquid	Density
Liquid 1	$4{\text{g cm}}^{-3}$
Liquid 2	$1{\text{g cm}}^{-3}$
Liquid 3	$10{\text{g cm}}^{-3}$

• A. $200{\text{cm}}^3$ in liquid 3
• B. Same in all the liquids
• C. $200{\text{cm}}^3$ in liquid 1
• D. $200{\text{cm}}^3$ in liquid 2

Answer 1

The correct option is B Same in all the liquids

The volume of the object dropped is irrespective of the density of the liquid.
So, when a stone of volume $200{\text{cm}}^3$ is dropped in each of the measuring cylinders, they all read the same reading.
The rise in volume in all the three measuring cylinders will be the same, i.e. $200{\text{cm}}^3$.
