In a U-tube if different liquids are filled then we can say that pressure at same level of same liquid is same.
Q. In a U-tube 20 cm of a liquid of density `rho` is on left hand side and 10 cm of another liquid of density 1.5 `rho` is on right hand side in between them there is a third liquid of density `2rho` what is the value of `h`.

A

5 cm

B

2.5 cm

C

2 cm

D

7.5 cm
