Section 5.5 Satellites in Circular Orbits
11. Two identical satellites are in orbit about
the earth. As the drawing shows, one orbit
has a radius r and the other 2r. The centrip-
etal force on the satellite in the larger orbit is
as that on the satellite in the smaller
orbit. (a) the same (b) twice as great (c) four
times as great (d) half as great (e) one-fourth
Earth
as great
