Q. The length of the tube of a microscope is $10\ cm$. The focal lengths of the objective and eye lenses are $0.5\ cm\ $and $1.0\ cm$. The magnifying power of the microscope is about
A) 5
B) 23
C) 166
D) 500
Explanation
(d) $m \simeq \frac{LD}{f_{o}f_{e}} \Rightarrow m = \frac{10 \times 25}{0.5 \times 1} = 500$
