In a simple astronomical telescope the focal length of the object glass is \( 0.75 \mathrm{~m} \) and that of the eye-piece is \( 0.05 \mathrm{~m} \).
\( \mathrm{P} \) Calculate the magnifying power when the final image of a distant

W object is seen (a) a long way off, (b) at a distance of \( 0.25 \mathrm{~m} \). Find the distance between the two lenses in each case.
