    There is a law called "Newton's law of universal gravitation" which states that the gravitational force between 2 objects is proportional to to the product of their masses and a constant G and inversely proportional to the square of the distance between them (their centers of mass), or : \[\ F= G \frac{m_1m_2}{r^2}\] where F- force between them(given) G - gravitational constant (given, I will assume it is, since you know it is earth) m_1- mass of the satellite(given) m_2 - mass of the Earth (also assuming it is given) r- distance between the center of earth and the satellite (this is what you need) Solve above equation for r and plug in the values.
