Q133 / 200 · NEET 2024 · Physics

A small telescope has an objective of focal length 140 cm and an eye piece of focal length 5.0 cm . The magnifying power of telescope for viewing a distant object is:

Correct answer
A
28
B
17
C
32
D
34

Solution

$f_0=140 \mathrm{~cm}$ and $f_e=5 \mathrm{~cm}$ For distant object, $m=\frac{f_0}{f_e}=\frac{140}{5}=28$

Hence, the correct answer is option: 'A'.
