Object O is kept in air in fron of a thin plano convex lens of radius of curvature 10cm. It's refractive index is `3//2` and the medium toward right of plane surface is water of refractive indec `4//3` . What should be the distance x of the object so that the rays become parrallel finall?  img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V04_C01_S01_095_Q01.png" width="80
