The maximum angular magnification of amagnifying glass is 12.0 when a person uses it who has a near point thatis 25.0 cm from his eyes. The same person finds that a microscope,using this magnifying glass as the eyepiece, has an angularmagnification of -525. The separation between the eyepiece and theobjective of the microscope is 23.0 cm. Obtain the focal length of theobjective.
