The figure represents a U-tube of uniform cross-section filled with two immiscible liquids. One is water with density `rho_(w)` and the other liquid is of density `rho` . The liquid interface lies `2 cm` above the base. The relation between `rho` and `rho_(w)` is
.

A

`rho=rho_(w)`

B

`rho=1.02rho_(w)`

C

`rho=1.2rho_(w)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A

`p_(1)=p_(2)`
`:. p_(0)+rho_(w)gh=p_(0)+rho gh`
` implies rho = rho_(w)`.
