Satellite 2
A 1.0 x 10^{3} kg satellite is in an orbit at a radial distance of 2 Earth radii. The satellite is then moved a little further away from Earth, to a radial distance of 3 Earth radii. Answer the following questions.
a) What is the magnitude of the
gravitational force acting on the satellite at 2R_{e} ? (2 marks)
b) What is the satellite's orbital velocity at 2R_{e} ? (2 marks) c) What is the satellite's orbital period at 2R_{e} ? (2 marks) d) What is the gravitational field strength at 2R_{e} ? (2 marks) e) What is the gravitational potential energy at 2R_{e} ? (2 marks) f) What is the satellite's kinetic energy at 2R_{e} ? (2 marks) 
g) How much work was required by an external agent to move the satellite from Earth's surface to 2R_{e}? (5 marks)
h) How much work was required by an external agent to move the satellite from 2 R_{e} to 3R_{e}? (2 marks)
