Answer:
3.62 x 10^15 N
Explanation: We will solve this problem by using Newton's Law of Universal Gravitation.
F = G m1*m2/ r^2 where
F= Force of attaction between each object
m1 and m2 the masses of the objects
r squared the distance between the objects
G= Gravitational constant
Working in the S.I the answar becomes:
F= 6.67x10^-11 * 3.1x10^20*7.4x10^18/(6.65x10^6)^2
F= 3.62 x 10^15 N
