Two converging lenses are placed 33.5 cm apart. The focal length of the lens on the right is 22.0 cm, and the focal length of the lens on the left is 10.5 cm . An object is placed to the left of the 10.5 cmfocal-length lens. A final image from both lenses is inverted and located halfway between the two lenses.
How far to the left of the 10.5 cm focal-length lens is the original object?
