A compound microscope is used to enlarge an object kept at a distance 
from it’s objective which consists of several convex lenses in contact and has focal length 
. If a lens of focal length 
is removed from the objective, then by what distance the eye-piece of the microscope must be moved to refocus the image
a)
2.5 
b)
6 
c)
15 
d)
9

(d) If initially the objective (focal length Now as in case of lenses in contact
So if one of the lens is removed, the focal length of the remaining lens system
This lens will form the image of same object at a distance
So to refocus the image, eye-piece must be moved by the same distance through which the image formed by the objective has shifted |
) forms the image at distance 
then 
such that
