A U-tube closed at one end is filled with three immiscible liquids having densities `rho, 3p and 8rho` as shown in figure. The pressure at point C inside the tube is:

A

`P_0+(hrhog)/3`

B

`P_0+(11hrhog)/3`

C

`P_0+(2hrhog)/3`

D

`P_0+hrhog`

Text Solution

Verified by Experts

The correct Answer is:
B
`P_A=P_B`
`P_0+hrhog+(2h)(3rho)g=P_("tube")+((2h)/3-h/4)(rho)g`
`P_0+7hrhog=P_("tube")+10/3hrhog`
`:. P_("tube")=P_0+11/3hrhog`
