max. magnification =1+(D/f) m =1+(25/2.5) m=1+10=11 m=11

Q. The maximum magnification that can be obtained with a convex lens of focal length $2.5 c m$ is (the least distance of distinct vision is $25 c m$ ).

max. magnification
$= 1 + \frac{D}{f}$ $m = 1 + \frac{25}{2.5}$
$m = 1 + 10 = 11$
$m = 11$
