To solve the problem step by step, we will use the lens formula and the magnification formula. ### Part (i): Finding the Object Distance (U) 1. **Identify the given values:** - Focal length (F) of the diverging lens = -15 cm (negative for concave lens) - Image distance (V) = -10 cm (negative because the image is virtual and on the same side as the object) ...
