Satellite A revolves around Earth 5 times a day. What is the radius of its orbit, measured from Earth's center? Assume that Earth generates the only significant gravitation attraction on the satellite. Note: The mass of Earth is 5.98 * 1024 kg, and the constant of universal gravity (G) equals 6.674 * 10-11 N · m2/kg2.

0.69 * 107 m

7.22 * 107 m

2.11 * 107 m

1.44 * 107 m
