Answer:
Mass of the Earth m1=6×1024kg
Mass of the Moon m2=7.4×1022kg
Distance between the Earth and the Moon d=3.84×105km=3.84×108m
Gravitational Constant G=6.7×10−11Nm2/kg2
Now, by using Newton’s law of gravitation
F=r2Gm1m2
F=(3.84×108)26.7×10−11×6×1024×7.4×1022
F=14.8225×1016297.48×1035
F=20.069×1019
F=20.1×1019N
Hence, the gravitational force of attraction is 20
