In an astronomical telescope, focal length of objective lens is `75 cm` and that of eye piece is `5 cm` . Calculate the magnifying power and the distance between the two lenses, when final image of distant object is seen at a distance of `25 cm` from the eye.

Explanation

To solve the problem step by step, we will calculate the magnifying power of the astronomical telescope and the distance between the two lenses.

### Step 1: Calculate the Magnifying Power (M)

The formula for the magnifying power of an astronomical telescope is given by:

\[
M = -\frac{F_O}{F_E} \left(1 + \frac{F_E}{D}\right)
