Question

There is a circular tube in a vertical plane. Two liquids which do not mix and of densities d1 and d2 are filled in the tube. Each liquid subtends 90 angle at centre. Radius joining their interface makes an angle α with vertical. Ratio of d1d2 is

Solution

The correct option is A

(1+tanα)(1tanα)


Equating pressure at the bottommost point from both sides, d1gR(1sin α)=d1gR(1cos α)+d2gR(sin α+cos α)d1d2=cos α+sin αcos αsin α=1+tan α1tan α
