An object 4.0 mm high is on the optical axis of two lenses with focal lengths f1 = +5.0 cm, f2 = +10 cm. The object is 6.5 cm to the left of the first lens, and the second lens is 31 cm to the right of the first lens. Find the position (relative to the second lens) and the size of the final image by calculation?
