Calculate the time period T of a satellite on equational orbit at 1.4×10em above the surface of the earth. b. What is the speed of the satellite in this orbit? c. If the satellite is travelling in the same direction as the rotation of the earth i.e. west to east, what is the interval between two successie times at which it will appear vertically overhead to an observed at a fixed point on the equator?

If T be the period of satellite revolving just above the surface of a planet whose average density is p show that PT2 is a universal constant.Read more on Sarthaks.com - https://www.sarthaks.com/128011/if-the-period-satellite-revolving-just-above-the-surface-of-planet-whose-average-density
