An astronomical telescope has an angular magnification of magnitude 5 for distant objects. The separation between the objective and the eyepiece is 36 cm. The final image is formed at infinity. The focal lengths $f_{0}$ of the objective and $f_{e}$ of the eyepiece are

Options:

Answer:

D

Solution:

$f_{o} / f_{e} = 5$ and $f_{o} + f_{e} = 36 cm$ .

$f_{e} = 6 cm, f_{o} = 30 cm .$
