Answer 1

Solution: Data : m1= 6×10 24 kg,m2 =7.4×10 22 kg,

r =3.84 ×10 5 Km = 3.84×10 8 m

G = 6.7 ×10 8 N.m 2 kg -2,F =?

F=Gm1m2/r2

6.7×10 -11N.m2 kg -2 ×6×10 24 kg ×7.4×10 22 kg

(3.84×10 8m)2

6.7×6×7.4×10 35= N=2.017×10 20 N

3.84×3.84×10 16

This is (the magnitude of)the gravitational force between the earth and the moon
