Question

Relative density of a solid is $0.6$. It floats in water with

• A. whole of its volume inside water
• B. $60\%$ volume inside water
• C. $60\%$ volume outside water
• D. $40\%$ volume inside water

Answer 1

The correct option is B

$60\%$ volume inside water

Explanation

1. Density is defined as mass per unit volume of a material substance.
2. Relative density is the ratio of the density of a substance to the density of water.
3. The Relative density is $0.6$.
4. So, $0.6\times 100\%=60\%$
5. This shows that $(100-60)\%$
6. $40\%$ which is volume floats with outside water.
7. It balances itself when it is $60\%$ submerged in water.

Hence, the correct option is (B).
