A compound microscope has an objective of focal length \( 2 \mathrm{~cm} \) and eye-piece of focal length \( 5 \mathrm{~cm} \). The distance between
P the two lenses is \( 25 \mathrm{~cm} \). If the final image is at a distance of

W \( 25 \mathrm{~cm} \) from the eye-piece, find the magnifying power of the microscope. What would be the magnifying power if the microscope were reversed?
