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.

The magnifying power of an astronomical telescope in the normal adjustment position is 100 . The distance between the objective and eye piece is 101 cm . Calculate the focal lengths of objective and eye piece.

The magnifying power an astronomical telescope in the normal adjustment position is 100. The distance between the objective and the eyepiece is 101 cm. calculate the focal length of the objective and the eyepiece.

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

The magnifying power of an astronomical telescope is 10 in normal adjustment and the corresponding tube length is 110 cm . Calculate the focal lengths of objective and eyepiece.

An astronomical telescope has a magnifying power of 10 . In normal adjustment, distance between the objective and eye piece is 22 cm calculate focal length of objective lens.

An astronomical telescope,when in normal adjustment has magnifying power 5.If the distance between two lenses is 24 cm,find the focal length of both the lenses.
