15. An object is placed at a distance xo =-1.5f in front of a convex lens of focal length f located at x 0. An identical object is placed at a distance x'o = -2f_ in front of a concave lens of focal length -f located at x' = 0. Find the difference between the two image positions (x'- X). Draw ray diagrams.
