The density of a material in CGS system ...

The density of a material in CGS system is `2g//cm^(3)`. In a system of units in which unit of length is `2` cm and unit of mass is `4` g what is the numerical value of the density of the material?

A

400

B

`0.04`

C

`0.4`

D

40

Text Solution

Verified by Experts

The correct Answer is:
D
`n_2=n_1[M_1/M_2]^(1)[L_1/L_2]^(-3)`
`=4[(1g)/(100g)][(cm)/(10 cm)]^(-3)=4 xx1/100 xx10^3 =40`
