1.	A magnifying glass of focal length 5cm is used to view an object by a person whose smallest distance of distinct vision is 25cm. If he holds the glass close to eye, then the magnification isA. 5B. 6C. 2.5D. 3
Answer» Correct Answer - B Given, f = 5 cm D = 25 cm `therefore` Magnification, `m=1+(D)/(f)` `m=1+(25)/(5)=6`
