Answer»

Explanation:There is no maximum LIMIT. An OBJECT at infinite distance will FORM an IMAGE at the other side of the lens at its 10cm focal length, and as you move the object closer the image moves away from the lens, until you can’t get the object closer because it touches the glass. Far before this happens, the image will be for practical purposes unusable. In photography it is rare to GO beyond where the image is the same size as the object, and rarer still to go beyond an image five times the size of the object.
