Question

The relative density of a solid is 0.6. It floats water with :

• A. whole of its volume inside water
• B. 60% volume inside water
• C. 60% volume outside water
• D. 40% volume inside water floats in water with

Answer 1

The correct option is B

60% volume inside water

Explanation for correct option(s):

Option (B) :

1. Relative density (RD) of a substance is defined as the ratio of the density of the substance to the density of water at $4^{O}C$.
2. $RD=\frac{densityofasubs\tan ce}{densityofwaterat{4}^{o}C}$
3. The relative density of solid is 0.6, which means that the solid is 60% more dense for an equal volume of water.
4. Hence, 60% of the volume of the solid is inside the water.

Hence, Option(B) is correct.
