Answer:
Step-by-step explanation:
N = Near point of eye = 25 cm
= Focal length of objective = 0.8 cm
= Focal length of eyepiece = 1.8 cm
l = Distance between the lenses = 16 cm
Object distance is given by
= Object distance for objective
From lens equation we have
The position of the object is
.
Magnification of eyepiece is
Magnification of objective is
Total magnification is given by
The total magnification is
.
