Question

The CGS unit of density is .

• A. $gc{m}^{-3}$
• B. $kg{m}^{-3}$
• C. $kgc{m}^{-3}$

Answer 1

The correct option is A $gc{m}^{-3}$

The CGS system takes centimetre, gram, and second as its fundamental units. Density being a derived quantity is a ratio of mass to volume.
$\Rightarrow$$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$
The CGS unit of mass and volume are $g$ and $c{m}^3$ respectively, which implies that the CGS unit of density is $gc{m}^{-3}$
