Final answer:

The telescope with an objective of 200 cm focal length and an eyepiece of 0.2 cm focal length has an angular magnification of 1000x.

Step-by-step explanation:

The magnification of a telescope is given by the ratio of the focal length of the objective lens to the focal length of the eyepiece. The formula for the angular magnification (M) is M = Fobj / Fep, where Fobj is the focal length of the objective lens and Fep is the focal length of the eyepiece lens.



In the provided question, the focal length of the objective lens (Fobj) is 200 cm and the focal length of the eyepiece (Fep) is 0.2 cm. Using the magnification formula, we get:



M = 200 cm / 0.2 cm = 1000



Therefore, the telescope with an objective lens of 200 cm focal length and an eyepiece of 0.2 cm focal length has an angular magnification of 1000x.
