A compound microscope has an objective of focal length `2.0 cm` and an eye-piece of focal length `6.25cm` and distance between the objective and eye-piece is `15cm`. If the final image is formed at the least distance vision `(25 cm)`, the distance of the object form the objective is

A

1.5cm

B

2.5cm

C

3.0cm

D

4.0cm

Text Solution

Verified by Experts

The correct Answer is:
B
`(-1)/mu_(0) + 1/v_(0) =1/f_(0)` (find `v_(0)`),`(-1)/u_(0)=1/f_(e)` find `u_(e)`
`m_(0)=v_(0)/u_(0),m_(e)`
