The attractive force F (in newtons, N) between two objects varies directly with the product of the masses of the objects (in kg) and inversely with the square of the distance between them (in meters). The Earth has a mass of 5.97 Γ1024 kg; the Moon has a mass of 7.35 Γ1022 kg; the distance between them is about 3.84 Γ108 meters; and they exert a gravitational force on each other of about 1.98 Γ1020 newtons. The distance between Earth and Mars is 5.46 Γ1010 meters at minimum, and Mars has a mass of about 6.42 Γ1023 kg. What is the gravitational force that the Earth and Mars exert on each other when they are closest to one another?
A. about 11.43 Γ 1016 newtons
B. about 11.88 Γ 1016 newtons
C. about 9.3 Γ 1016 newtons
D. about 8.55 Γ 1016 newtons
