    I have been working on this problem for HOURS!!! PLease helpe me!!!!!

    1. The problem statement, all variables and given/known data
    The objective of a telescope has a focal length of 200 cm and its eye piece has a focal length of 1 cm. What is the magnification of this telescope when viewing an object at infinity???????

    2. Relevant equations

    3. The attempt at a solution

    I thought ...
    M = Fo/Fe which would = 200 but the answer is 20! Why?!?!? Does infinity have something to do with it??
