The focal lengths of the objective lens and the eyepiece of a microscope are 0.50 cm and 2.0 cm, respectively, and their separation is 6.0 cm when adjusted for minimum eyestrain for a person with a near point of 25.0 cm.

If the microscope is focused on a small object, the magnitude of its final overall magnification is closest to
A) 200. B) 150. C) 50. D) 100. E) 250.

Question 2
