The magnifying power of an astronomical telescope is 8 and the distance between the two lenses is `54 cm`. The focal length of eye lens and objective lens will be respectively

The magnifying power of an astronomical telescope is 8 and the distance between the two lenses is 54 cm. The focal length of eye lens and objective will be respectively.

The magnifying power of an astronomical telescope for relaxed vision is 16 and the distance between the objective and eyelens is 34 cm. Then the focal length of objective and eyelens will be respectively

The magnifying power of an astronomical telescope is 5 . When it is set for normal adjustment, the distance between the two lenses is 24 cm . Calculate the focal lengths of eye piece and objective lens.
