A converging lens (f1 = 26.0 cm) is placed 58.0 centimeter to the left of a diverging lens (f2 = -30.0 cm). An object is located to the left of the converging lens, and the final image produced by the two-lens combination lies 20.8 centimeter to the left of the diverging lens. Determine how far is the object from the converging lens?
