Final answer:
To increase the orbital period of a satellite, you need to increase its altitude. The mass of the satellite has negligible effect on the period, and changing the universal constant G is not feasible.
Step-by-step explanation:
To increase the orbital period of a satellite in a low earth orbit, one would need to increase the height of the satellite above the surface. When the satellite's altitude is increased, the gravitational force acting upon it decreases, which leads to a reduction in its orbital velocity according to the conservation of angular momentum. As a result, the orbital period, which is the time taken for the satellite to complete one orbit around Earth, increases. Changing the satellite's mass or the value of G, the gravitational constant, is not practical and does not directly affect the orbital period in the same manner as changing the altitude.
Discussion of Mass and G
Even though increasing the mass of the satellite might seem like it would affect the period, the fact remains that the satellite's mass is small compared with that of Earth, and thus the satellite's mass does not significantly influence the orbital period. Moreover, changing the value of G is not possible as it is a universal constant.
