A card sheet divided into squares each of size `1 mm^2` is being viewed at a distance of 9 cm through a magnifying glass (a converging lens of focal length 10 cm) held close to the eye. What should be the distance between the object in converging lens and the magnifying glass if the virtual image of each square in the figure is to have an area of `6.25 mm^2`. Would you be able to see the squares distinctly with your eyes very close to the magnifier ?
