A wire mesh consisting of very small squares is viewed at a distance of 8 cm through a magnifying converging lens of focal length 10cm, kept close to the eye. The magnification produced by the lens is
Lens formula is given by
Where 
is focal length of lens,
is image distance and 
is object distance.
Given 
(as lens is converging)
(as object is placed on left side of the lens)
Substituting these values in Eq. (i) , we get
Hence, magnification produced by the lens
