A thin uniform tube is bent into a circle of radius

r

in the vertical plane. Equal volumes of two immiscible liquids, whose densities are

{\rho _1}

and

{\rho _2}

\left( {{\rho _1} > {\rho _2}} \right),

fill half the circle. The angle

\theta

between the radius vector passing through the common interface and the vertical is :
