Mars (6800 km diameter) is viewed through a telescope on a night when it is 1.1
Question:
Mars (6800 km diameter) is viewed through a telescope on a night when it is 1.1 × 108 km from the earth. Its angular size as seen through the eyepiece is 0.50°, the same size as the full moon seen by the naked eye. If the eyepiece focal length is 25 mm, how long is the telescope?
