Question
Two satellites of equal masses are orbiting the earth in different orbits. Will their moment of inertia be same or different?
Solution
The satellite orbiting around the earth can be considered as particle.
The moment of inertia about earth = MR2.
Therefore, the satellite in outer orbit has more moment of inertia than that of satellite in inner orbit.
The moment of inertia about earth = MR2.
Therefore, the satellite in outer orbit has more moment of inertia than that of satellite in inner orbit.
