A narrow U-tube placed on a horizontal surface contains two liquids of densities `rho_(1)` and `rho_(2)` . The columns of the liquids are indicated in the figure. The ratio `(rho_(1))/(rho_(2))` is equal to :

A

`(1)/(3)`

B

`(2)/(5)`

C

`(1)/(2)`

D

`(4)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
B
Equating the pressure at the bottom of both limbs,
`P_(0)+rho_(1)g(5)+rho_(2)g(4)=P_(0)+rho_(2)g(6)implies(rho_(1))/(rho_(2))=(2)/(5)`
