A typical red blood cell subtends an angle of only 1.8×10^-5 rad when viewed at a person's near-point distance of 25 cm. Suppose a red blood cell is examined with a compound microscope in which the objective and eyepiece are separated by a distance of 13.0cm. Given that the focal length of the eyepiece is 2.7cm, and the focal length of the objective is 0.48cm, find the magnitude of the angle subtended by the red blood cell when viewed through this microscope.
