Q138 / 180 · AIIMS 2018 (26 May) · Physics

In a simple microscope of focal length $5 \mathrm{~cm}$, final image is formed at the least distance of distinct vision, then its magnification will be

Correct answer
A
$6$
B
$5$
C
$2$
D
$1$

Solution

$M=1+\frac{D}{f}=1+\frac{25}{5}=6$

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