Two convex thin lenses with focal lengths 10.0 cm and 20.0 cm are aligned on a common axis, running left to right, the 10-cm lens being on the left. a distance of 20.0 cm separates the lenses. an object is located at a distance of 15.0 cm to the left of the 10-cm lens. where will the final image appear as measured from the 20-cm lens? (a) -13.3 cm (b) -6.67 cm (c) +6.67 cm (d) +13.3 cm (e) +8.1 cm
