      Explain why the cities of Mumbai and Chennai are able to see the noon Sun exactly overhead twice a year, but Delhi never sees it exactly overhead.                 

    Answer:

                      Mumbai and Chennai are South of the Tropic of Cancer (23.30' N), while Delhi is North of it. Due to the tilt of the axis of rotation of the Earth by 23.5°, parts of the Earth North of the Tropic of Cancer will never have the noon Sun exactly overhead. Parts to its South will have the noonday Sun exactly overhead twice a year, between the time of the Vernal Equinox in March and the Autumnal Equinox in September.
