The distance between the eyepiece and the objective lens in a certain compound microscope is 27.7 cm. The focal length of the objective is 0.490 cm, and that of the eyepiece is 1.60 cm. Find the overall magnification of the microscope. (The near point of the eye is 25 cm. Assume that the object is placed at the focal point of the objective lens, and one places the eyepiece at the near point of the eye.)
