The height (in km) of the orbit above the surface of the earth in which a satellite, if placed, will appear stationary is

A satellite of mass 10 kg is placed initially in a temporary orbit 800 km above the surface of earth. The satellite is to be placed now in a permanent orbit at 2000 km above the surface of earth. Find the amount of workdone to move the satellite from temporary to permanent orbit. The radius of the earth is 6400 km and g = 10 ms^(-2) .

The height of geostationary orbit above the surface of the earth is h. Radius of the earth is R. The earth shrinks to half its present radius (mass remaining unchanged). Now hat will be height of a geostationary satellite above the surface of the earth?

The height of a geo-stationary satellite above the centre of the earth is ( in KM )

A geostationary satellite is orbiting the earth at a height of 5R above the surface of the earth, R being the radius of the earth. The time period of another satellite in hours at a height of 2R form the surface of the earth is

A satellite is to be put into an orbit 600 km above the surface of the earth. If its vertical velocity after launching is 2400 m//s at this height, calculate the magnitude and direction in the impulse required to put the satellite directly increase. The mass of the satellite is 60 kg and the radius of the earth is 6400 km . Take g=10 ms^(-2)

A geostationary satellite is orbiting the earth at a height of 6R above the surface of the earth, where R is the radius of the earth. The time period of another satellite at a height of 2.5 R from the surface of the earth is …… hours.

If the length of the day is T, the height of that TV satellite above the earth's surface which always appears stationary from earth, will be :

A satellite ils launched into a circular orbit 1600km above the surface of the earth. Find the period of revolution if the radius of the earth is R=6400km and the acceleration due to gravity is 9.8ms^(-2) . At what height from the ground should it be launched so that it may appear stationary over a point on the earth's equator?
