During the lunar mission of Apollo 11, two astronauts (Armstrong and Aldrin) descended to the moon's surface in the lunar module while a third astronaut (Collins) remained in orbit in the command module: the command module's period was 2 hours and 20 minutes. Which of the following is closest to the height of the command module above the surface of the moon in this orbit? (Use MMoon= 7.35 x 1022kg, RMoon= 1.74 x 106 m,  and G= 6.67 x 10-11N.m2.kg-2  and neglect the gravitational effects of the earth on the motion of the commons module).
