A terrestrial telescope has objective and eyepiece lenses of focal length 200 cm and 5 cm, respectively. The erecting lens has a focal length of 4.5 cm. Calculate the separation between the objective and the eyepiece. Also calculate the magnifying power of the telescope.

Explanation

To solve the problem of finding the separation between the objective and the eyepiece of a terrestrial telescope and calculating its magnifying power, we can follow these steps:

### Step 1: Identify the given data
- Focal length of the objective lens, \( f_o = 200 \, \text{cm} \)
- Focal length of the eyepiece lens, \( f_e = 5 \, \text{cm} \)
- Focal length of the erecting lens, \( f_r = 4.5 \, \text{cm} \)

### Step 2: Calculate the separation between the objective and the eyepiece
