You are given two converging lenses of focal lengths 1.25 cm and 5cm to design a compaound microscope.if it is desired to have a magnification of 30, find out the separation between the object and the eyepiece.
or
A small telescope has an objective lens of focal length 150 cm and eyepiece of focal length 5 cm. What is the magnifying of the telescope for viewing distant objects on normal adjustment ?
If this telescope is used to view a 100 m tall tower 3 km away, what is the height of the image of the tower formed 3km away, what is the height of the image of the tower formed by the objective lens ?

Explanation

### Step-by-Step Solution

#### Part 1: Designing a Compound Microscope

1. **Given Data:**
- Focal length of the eyepiece (Fe) = 5 cm
- Focal length of the objective lens (Fo) = 1.25 cm
- Desired magnification (M) = 30
