Suppose We Want a Satellite to Revolve Around the Earth

Suppose we want a satellite to revolve around the earth 5 times a day. What should be the radius of its orbit? (The mass of the earth is 5.97 × 10²⁴ kg, G = 6.67 × 10^-11 N ∙ m²/kg², and you can neglect the presence of the moon.)

A) 1.44 × 10⁷ m
B) 0.690 × 10⁷ m
C) 7.22 × 10⁷ m
D) 2.11 × 10⁷ m
