The distance between the objective and eyepiece lenses in a microscope is 25\; cm . The objective lens has a focal length of 6.00\; mm and the eyepiece lens has a focal length of 7.5\; cm.
1. If the object is placed 6.20\; mm in front of the objective lens, where is the final image formed?
2. What is the total linear magnification for the microscope?
3. What is the overall angular magnification for the microscope if the eye is placed at the second lens?
