Quizplus · Accepted Answer

The magnification of a telescope can be calculated by dividing the focal length of the objective by the focal length of the eyepiece.

Magnification = Focal length of objective / Focal length of eyepiece
Magnification = 200 cm / 2.0 cm
Magnification = 100 times

Therefore, the correct answer is C) 100 times.
