Gauge Cardenas · Answer 1

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
