Question

The density of a material in CGS system of units is 10 g/cm3. In a system of units in which unit of length is 10 cm and unit of mass is 50g. What is the density of material?​

Answer 1

Explanation:

In CGS, d=4

cm

3

g

If unit of mass is 100 g, 4 g mass in new units is

100

4

units

and unit of distance is 10 cm, 1 cm in new units is

10

1

units

So, density =

(

10

1

cm)

)

=
