Question

Two satellites A and B are orbiting the earth around the equator, E, at different altitudes on a circular path of 2400km and 3000km from the surface of the earth. The radius of the earth at the equator is its equatorial radius which is 6378km, mass of the earth is 5.98*10^24kg, g=9.81m/s^2, G=m^2/kg^2. If the satellites are of the same mass, 100kg, determine the:
a) Force required to keep each satellite in orbit.
b) Speed of the satellite and which is at a higher speed around the earth.
c) The period and the angular frequency of the satellites around the earth.
d) Force of attraction between the earth and each satellite, fA and fB.
