A converging lens (f1 5 24.0 cm) is located 56.0 cm to the left of a diverging lens (f2 5 228.0 cm). An object is placed to the left of the converging lens, and the fi nal image produced by the two-lens combination lies 20.7 cm to the left of the diverging lens. How far is the object from the conver
