How Do You Calculate Acceleration Due to Gravity at a Distance from Earth?

[Jyote25]

Homework Statement

An object(mass=525kg) is 3.0x10³ km above the Earth's surface. This object is falling toward the Earth because of the Earth's gravitational force on it. What is the rate of acceleration when it is at this distance?

Homework Equations

Mass of Earth=5.98x10²⁴
Radius of Earth=6.37x10⁶
Fg=Gm₁m₂/r²

g=Gm/r²
