A Galileo telescope has an objective of focal length `100cm` and magnifying power 50. The distance between the two lenses in normal adjustment will be

A

`98 cm`

B

`100cm`

C

`150cm`

D

`200 cm`

Text Solution

Verified by Experts

The correct Answer is:
A
`m=(f_(o))/(f_(e))implies(100)/(f_(e))=50impliesf_(e)=2cm`
Normal distance `f_(o)-f_(e)=100-2=98cm`
