What is the distance of distinct vision?

The focal length of the objective and of the eye- piece of compound microscope are f_(0) and f_(e) respectively. If L is the tube length and d, the least distance of distinct vision, then its angular magnification, when the image is formed at infinity, is

Magnification at least distance of distinct vision is 25 cm of a simple microsope of focal length 5 cm is

The total magnification produced by a compound microscopeis 20. The magnification produced by the eye piece is 5. The microscope is focussed on a certain object. The distance between the objective and eyepiece is observed to be 14 cm. If least distance of distinct vision is 20 cm, calculate the focal length of the objective and the eye piece.

A compound microscope consists of an objective lens of focal length 2.0 cm and an eyepiece of focal length 6.25 cm separated by a distance of 15 cm.
