Calculate the force of gravity on the 0.90-kg mass if it were 6.4×106 m
above Earth's surface (that is, if it were two Earth radii from Earth's center).
Express your answer to two significant figures and include the appropriate units.

Answer:

Explanation:

Doubling the distance reduces the gravity force by four.

F = 0.90(9.8/4) = 2.205 = 2.2 N

could also use F = GmM/r²

F = 6.674e-11(0.90)(5.972e24) / (6.4e6 + 6.4e6 )² = 2.1894... = 2.2 N
