An object is placed at `f//2` away from first focus of a convex lens where f is the focal length of the lens. Its image is formed at a distance `3f//2` in a slab of refractive index `3//2` , from the face of the slab facing the lens. Find the distance of this face of the slab from the second focus of the lens.
