A telescope has magnifying power 5 and length of tube is 60cm then the...
m = fo/fe
5 = fo/fe
fo = 5fe
fo + fe = 60
6fe = 60

To find the focal length of the eyepiece, we can use the formula for the magnifying power of a telescope:
Magnifying Power = (Focal Length of Objective Lens) / (Focal Length of Eyepiece)
Given that the magnifying power is 5, we can rearrange the formula to solve for the focal length of the eyepiece:
Focal Length of Eyepiece = (Focal Length of Objective Lens) / (Magnifying Power)
Since the length of the tube is not needed to calculate the focal length of the eyepiece, we can disregard that information.
Without knowing the focal length of the objective lens, we cannot determine the focal length of the eyepiece.
