    The maximum magnification that can be obtained with a convex lens of focal length \[2.5\,\,cm\] is least distance of distinct vision is \[25\,\,cm\]

    A) \[10\]                                   

    B) \[0.1\]

    C)  \[62.5\]                                              

    D)  \[11\]

    Correct Answer: D

    Solution :

    Maximum magnification is obtained when image is formed at near point of eye. In that case                 \[m=I+\frac{D}{f}=1+\frac{25}{2.5}=11\]
