Satellites in Circular Orbit

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?

Energy of a satellite in circular orbit is E_(0) . The energy required to move the satellite to a circular orbit of 3 times the radius of the initial orbit is

The period of a satellite in a circular orbit of radius R is T. What is the period of another satellite in a circular orbit of radius 4 R ?

Energy of a satellite in circular orbit is E_(0) . The energy required to move the satellite to a circular orbit of 3 time the radius of the initial orbit is (x)/(3)E_(0) . Find the value of x.

Match the Column I with Column II For a satellite in circular orbit (where M_(E) is the mass of the earth , m is the mass of the satellite and r is the radius of the orbit )

The time period of an artificial satellite in a circular orbit of radius R is 2 days and its orbital velocity is v_(0) . If time period of another satellite in a circular orbit is 16 days then

The time period of a satellite in a circular orbit around the earth is T . The kinetic energy of the satellite is proportional to T^(-n) . Then, n is equal to :
