There is small air bubble inside a glass sphere (mu=1.5) of radius 10 cm. The bubble is 4.0 cm below the surface and is viewed normally from the outside figure. Find the apparent depth of the bubble

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.
