The near point of a naked eye is 21 cm. When placed at the near point and viewed by the naked eye, a tiny object would have an angular size of6.0 × 10-5 rad. When viewed through a compound microscope, however, it has an angular size of -7.9 × 10-3 rad. (The minus sign indicates that the image produced by the microscope is inverted.) The objective of the microscope has a focal length of 2.8 cm, and the distance between the objective and the eyepiece is 19 cm. Find the focal length of the eyepiece.
