Calculate the force of gravity on a 12 kg mass if it were 6.4 106 m above Earth's surface (that is, if it were 2 Earth radii from Earth's center.)

Think about the inverse square law. At two earth radii from center, the weight force is REDUCED by a factor of 2^2.
Don't forget to convert mass (kg) to force (N)
