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
.

The figure shown a pipe of uniform cross-section inclined in a vertical plane. A U-tube manometer is connected between the point A and B. If the liquid of density rho_(0) flows with velocity v_(0) in the pipe. Then the reading h of the manometer is

A cubical block of density rho floats completely immersed in two non-mixing liquids of densities rho _ 1 and rho _ 2 as shown in figure. The relation between rho , rho_1 and rho _ 2 is :

A body of density rho sinks in a liquid of density rho_(L) .The densities rho and rho_(L) are related as:

A circular tube of uniform cross section is filled with two liquids densities rho_(1) and rho_(2) such that half of each liquid occupies a quarter to volume of the tube. If the line joining the free surfaces of the liquid makes an angle theta with horizontal find the value of theta.
