There is a circular tube in a vertical plane. Two liquids which do not mix and of densiities `d_(1) and d_(2)` are filled I the tube. Each liquid subtends `90^(@)` angle at centre. Radius joining their interface makes an angle `alpha` with vertical. Ratio `d_(1)//d_(2)` is

A

`(1+ tan alpha)/(1-tan alpha)`

B

`(1+sin alpha)/(1- cos alpha)`

C

`(1+sin alpha)/(1- sin alpha)`

D

`(1 + cos alpha)/(1-cos alpha)`

There is a circular tube in a vertical plane. Two liquids which do not mix and of densities d_1 and d_2 are filled in the tube. Each liquid substends 90^@ angle at centre. Radius joining their interface make an angle alpha with vertical. Ratio (d_1)/(d_2) is :

A thin uniform circular tube is kept in a vertical plane. Equal volume of two immiscible liquids whose densites are rho_(1) and rho_(2) fill half of the tube as shown. In equilibrium the radius passing through the interface makes an angle of 30^(@) with vertical. The ratio of densities (rho_(1)//rho_(2)) is equal to

If equal masses of two liquids of densities d_(1) and d_(2) are mixed together, the density of the mixture is

A uniform long tube is bent into a circle of radius R and it lies in vertical plane. Two liquids of same volume but densities rho " and " delta fill half the tube. The angle theta is

A small uniform tube is bent into a circle of radius r whose plane is vertical. Equal volumes of two fluids whose densities are rho and sigma(rhogtsigma) fill half the circle. Find the angle that the radius passing through the interface makes with the vertical.

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) (rho_(1) gt rho_(2)) fill half the circle. The angle theta between the radius vector passing though the common interface and the vertical is :

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.
