Focal length of objective and eye piece of telescope are 200 cm and 4 cm respectively. What is the length of telescope for normal adjustment?

A

`196` cm

B

`204` cm

C

`250` cm

D

`225` cm

Text Solution

Verified by Experts

The correct Answer is:
B
In normal adjustment,
`L=f_(0)+f_(e)=200` cm `+4` cm =`204` cm
