An object is seen thorugh a simple microscope of focal length 12 c. Find the angular mgnification produced if the image is formed at the near pointofhe eye which is 25 cm away from it.

A

37/12

B

25/12

C

Both

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
The angular magnification produced by a simple microscope when the image is formed at the near point of the eye is given by
`m=1+(D)/(f)`
Here `f =12 cm,D=25 cm`
Hence `m-1 +(25)/(12) =3.08`.
