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.

Text Solution
