Consider earth satellites in circular orbits. A geostationary satellite must be at a height of about 36000 km from the earth's surface. Will any satellite moving at this height be a geostationary satellite? Will any satellite moving at this height have a time period of 24 hours?

STATEMENT -1 : The orbital speed of geostationary satellite is nearly 3.1 km/s. STATEMENT -2 : The rotation of geostationary satellite around earth is from west to east. STATEMENT -3 : The total mechanical energy of an orbiting satellite is smaller than its kinetic energy.
