the density of a material is 8 g/cc. In a system in which units of length is 5 cm and of mass is 20 g, the density of material is :

A

8

B

20

C

50

D

80

Text Solution

Verified by Experts

The correct Answer is:
C
`n_(1)u_(1)=n_(2)u_(2)`
`therefore" "n_(2)=n_(1)(u_(1))/(u_(2))=8[(1)/(20)][(5)/(1)]^(3)=50.`
