A Ramsden eyepiece consists of two positive lenses of focal length 2 cm each and the lenses separated by 2 cm. Determine the magnifying power of the above ocular when viewing an image at infinity. (Magnifying power of a lens of focal length / observing a distant object is given by, M =25/f where f is in cm.)
