Given information
It is given that the altitudes of and are two satellites orbiting the Earth. Assuming the velocity of satellite at be and the velocity of satellite at be .
Step-by-step explanation
Step 1.
We know that the velocity of the satellite bounded by Earth's gravitational force is given by
Here, is the mass of Earth, is the universal gravitation constant and is the distance between the center of earth to the satellite.
It is clear that the velocity of the satellite is inversely proportional to the square root of its altitude,
so,
