To solve the problem, we need to find the magnification power of a converging lens (convex lens) with a focal length of 8 cm when it is used as a reading lens to form an image at the near point (25 cm). ### Step-by-Step Solution: 1. **Identify the given values:** - Focal length of the lens (f) = +8 cm (positive because it is a converging lens) - Image distance (v) = -25 cm (negative because the image is formed on the same side as the object, which is typical for a virtual image in a reading lens) ...
