Question

Density of metal $\left(kg/m^3\right)$	Density of water $\left(kg/m^3\right)$	Relative density
..............	${10}^3$	5
$8.5\times {10}^3$	${10}^3$	..............

Complete the following.

• A. $5\times {10}^3,8.5$
• B. $5,8.5$
• C. $5\times {10}^3,{10}^3$
• D. $5,8.5\times {10}^3$

Answer 1

Answer: (A)

$5\times {10}^3,8.5$

Relative density = $\frac{Densityofmetal}{Densityofwater}$

So, 5 = $\frac{Densityofmetal}{{10}^3}$

$Densityofmetal=5\times {10}^{3}kg/m^3$

Relative Density, $R.D.=\frac{8.5\times {10}^3}{{10}^3}$

$R.D.=8.5$
