Classical Mechanics Level 2

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 subtends \(90^\circ \) angle at centre. Radius joining their interface makes an angle \( \alpha \) with vertical. Ratio \( \frac {d_1}{d_2 } \) is:
