Q4 of 52 Page 432

A child has near point at 10 cm. What is the maximum angular magnification the child can have

with a convex lens of focal length 10 cm?


Given data-


Focal length of the convex lens ,f = 10cm


Near point of the eyes ,D = 10cm


The maximum angular magnification of the child when the image is formed at distance D=10cm


is






Hence, the angular magnification is 2.0 when the near point is 10cm
