There is small air bubble inside a glass sphere (mu = 1.5) of radius 5 cm . The bubble is at 'O' at 7.5cm below the surface of the glass. The sphere is placed inside water (mu = (4)/(3)) such that the top surface of glass is 10cm below the surface of water. The bubble is viewed normally from air. Find the apperent depth of the bubble.
