The minimum angular magnification of an astronomical telescope is 10 the length of it's tube is 44cm determine the focal length of the lenses in normal adjustment

kindly follow the link:

if u still have any doubt feel free 2 ask :))

Dear student 
The ans given by ADITYA  is incorrect , It is not as per question.
Magnifying power of astronomical telescope = Focal length of Objective/Focal length of eye piece M = f0/fe ....(i) Distance between two lenses = Focal length of eye - piece + Focal length of the objective.
d = fe + f0 
M = 10 
d = 44 
f0/fe = 10 
f0 = 10fe 
11fe = 44 
fe = 4 cm 
f0 = 44 cm 
fe = 4 cm 
Hope this will help 
Good Luck
