Two satellites of equal masses, which can be considered as particles are orbiting the earth at different heights. Will their moments of inertia be same or different?

Answer:

                Moments of inertia of the two satellites will be different. This is because, I = mass × (distance)2. For the satellite revolving at a greater height, distance from the axis of rotation is larger. Therefore, its moment of inertia is larger.
