Final answer:
The angular magnification of the image on the retina is calculated by dividing the angle subtended by the image with the angle subtended by the object, resulting in a magnification of 6.
Step-by-step explanation:
The magnification of an image is given by the ratio of the angle subtended by the image to the angle subtended by the object. In this case, the image on the retina subtends an angle of 30° and the object subtends an angle of 5°. Therefore, the angular magnification of the image is calculated as follows:
Magnification (M) = (angle subtended by the image) / (angle subtended by the object) = 30° / 5° = 6.
Thus, the magnification of the image formed on the retina is 6 times larger than the object.
