Question

Three objects A, B, and C are in a liquid, as shown. Arrange them in the correct order of density, from the lowest to the highest.

• A. $\text{B}>\text{A}>\text{C}$
• B. $\text{B}<\text{A}<\text{C}$
• C. $\text{B}=\text{A}<\text{C}$
• D. $\text{B}>\text{A}=\text{C}$

Answer 1

The correct option is B $\text{B}<\text{A}<\text{C}$

The object that completely sinks in water has more density than the water. So, C has the highest density among the three objects.

A and B are floating, so their density is lower than water. Among A and B, larger fraction of A is immersed in water as compared to B. So, A has higher density than B.

So, arranging the bodies in the decreaing order of densities, we get the following order:
$\text{B}<\text{A}<\text{C}$
