When a loaded test tube floats vertically with `1/3` and `1/4` of the lengths inside two liquids, then the ratio of the densities of the two liquids is

A

`3:4`

B

`4:3`

C

`9:16`

D

`16:2`

Text Solution

Verified by Experts

The correct Answer is:
A
`Axx l/3 rho_(1)g = A xx l/4 rho_(2)g or (rho_1)/(rho_2) = l/4 xx 3/l = 3/4` .
