There is a circular tube in a vertical plane. Two liquids are filled in the tube whose densities are given by
373kg/m3 and
100kg/m3 respectively . It is observed that the liquids do not mix and each liquid subtends an angle of
90∘ at the centre. Radius joining their interfaces makes an angle
α with the vertical as shown in figure. Find the value of
α (in degrees) is
