The near point of a naked eye is 32 cm. When an object is placed at the near point and viewed by the naked eye, it has an angular size of 0.068 rad. A magnifying glass has a focal length of 15 cm, and is held next to the eye. The enlarged image that is seen is located 63 cm from the magnifying glass. Determine the angular size of the image.
