A satellite is put into a circular orbit with the intention that it over a certain spot on the earths surface However the satellite's orbital radius is erroneously made `1.0km` large for this to happen At what rate and direction does the point directtly below the satellite move across the earth surface ltbgt R =Radius of earth = 6400km
r= radius of orbit of geostationary satellite = 42000km
T= Time period of earth about its axis = 24hr .

Answer

`V_(rel) = (3DeltarRpi)/(rT) = (pi)/(189)m//sec ~~ 1.66 cm//sec`
to the east along equator .
