To solve the problem of finding the position of the final image formed by the combined system of a convex lens and a concave lens, we can follow these steps: ### Step 1: Identify the lenses and their properties - **Convex Lens**: Focal length (F1) = +10 cm (positive because it converges light) - **Concave Lens**: Focal length (F2) = -10 cm (negative because it diverges light) - The distance between the two lenses (d) = 5 cm. ### Step 2: Determine the object distance for the convex lens ...
