The focal lengths of the objective and the eye-piece of an astronomical telescope are 0.25 m and 0.02m, respectively. The telescope is adjusted to view an object at a distance of 1.5 m from the objective, the final image being 0.25 m from the eye of the observer. Calculate the length of the telescope and the magnification produced by it.
