Consider a Satellite in a Circular Orbit Around the Earth

Question 46

Multiple Choice

Consider a satellite in a circular orbit around the Earth. If it were at an altitude equal to twice the radius of the Earth, 2RE, how would its speed v relate to the Earth's radius RE, and the magnitude g of the acceleration due to gravity on the Earth's surface?


A) Consider a satellite in a circular orbit around the Earth. If it were at an altitude equal to twice the radius of the Earth, 2R<sub>E</sub>, how would its speed v relate to the Earth's radius R<sub>E</sub>, and the magnitude g of the acceleration due to gravity on the Earth's surface? A)    B) v<sup>2</sup> = 2gR<sub>E</sub> C)    D)    E)
B) v2 = 2gRE
C) Consider a satellite in a circular orbit around the Earth. If it were at an altitude equal to twice the radius of the Earth, 2R<sub>E</sub>, how would its speed v relate to the Earth's radius R<sub>E</sub>, and the magnitude g of the acceleration due to gravity on the Earth's surface? A)    B) v<sup>2</sup> = 2gR<sub>E</sub> C)    D)    E)
