In $CGS$ system of units, the density of a material is $4 g {cm}^{- 3}$ . What will be the value of the density of the material in a system of units in which unit of length is $10 cm$ and unit of mass is $100 g$ ?

Options:

Answer:

Solution:

As $n_{1} u_{1} = n_{2} u_{2}$

$4 g {cm}^{- 3} = n_{2} \frac{100 g}{{(10 cm)}^{3}}$

$\Rightarrow n_{2} = 40$
