An astronomical telescope has objectives and eye-piece lenses of focal length 3.5m and 5cm respectively. Determine the magnifying power of the telescope when in normal adjustment
A
70.0
B
17.5
C
7.0
D
0.7
correct option: a
Magnify power = \(\frac{f_o}{f_e}\)
= \(\frac{3.5 \times 100}{5.0}\)
= 70
= \(\frac{3.5 \times 100}{5.0}\)
= 70
