Compute the all parts of following problem given below:
Problem: Two lenses, one converging with focal length 21.5cm and one diverging with focal length 12.0cm, are placed 25.0cm apart. An object is placed 60.0cm in front of the converging lens.
Part I: Find the final image distance from second lens. Follow the sign conventions.
Part II: Determine the magnification of the final image formed. Follow the sign conventions.
Please explain how you obtained the answer. Thanks.
