A refracting telescope, like a compound microscope, contains two converging lenses, the objective lens and the eyepiece

Question:

A refracting telescope, like a compound microscope, contains two converging lenses, the objective lens and the eyepiece lens, positioned on a common optical axis (Figure 33.49). However, a telescope is designed to view large, very distant objects, whereas a microscope is used to view very small objects that are placed very close to the objective lens. Consequently, the arrangement of lenses in a telescope is different from the arrangement in a microscope. The telescope's objective lens is positioned to form a real image of very distant objects, and the eyepiece lens is positioned to form a virtual image of the image produced by the objective lens, to be viewed by an observer.

(a) How should the lenses be arranged to accomplish this?

\((b)\) What is the overall magnification produced by the telescope?
