Is it possible to put an artificial satellite into an orbit in such a way that it will always remain direct over a city (I mean at any specific place)?

    $\begingroup$ No, Physics.StackExchange is not a homework help site. Please see this Meta post on asking homework questions. People probably gave this a downvote because you could have easily found this information by using Google. $\endgroup$ – Kyle Kanos Nov 25 '14 at 17:26

    $\begingroup$ No. See the answer of @DirkBruere $\endgroup$ – garyp Nov 25 '14 at 17:43

The answer is "No" - unless the city is on the equator. You specified "...it will always remain direct over a city". Satellites in geosync orbit might be visible to cities but not be directly overhead unless they are located on the equator.
