Consider a two-lens system consisting of a diverging lens (f=-27.0 cm) and a converging lens (f=22.0 cm). An object is placed 7.0 cm to the left of the converging lens and a final image is produced by the two-lens system that is 20.0 cm to the left of the diverging lens. If the converging lens is to the left of the diverging lens, how far apart are the two lenses?
