    A child has near point 12 cm. The maximum angular magnification, the child can have with a convex lens of focal length 12 cm?

    A)  1.7                                        

    B)  1.0

    C)  2.0                                        

    D)  2.5

    Correct Answer: C

    Solution :

                    The near point\[D=12\text{ }cm\]and focal length, \[f=12\text{ }cm\] The maximum angular magnification is obtained when the image is formed at the near point, So,          \[m=1+\frac{D}{f}=1+\frac{12}{12}=1+1=2\]
