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

96 cm

B

98 cm

C

102 cm

D

104 cm

Text Solution

Verified by Experts

The correct Answer is:
C
`f_(o) = 100 `cm, m = 50
`m = (f_(o))/(f_(e)) rArr f_(e) = (100)/(50) = 2` cm
L= `f_(o) + f_(e) = 102` cm.
