Calculate the force of gravity on the 1.4-kg mass if it were 1.3×107 m above Earth's surface (that is, if it were three Earth radii from Earth's center).

it may be wrong but i think its a

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
