Answer 2

Answer:

Given that,

Mass of the Earth m 1

=6×10 24 Kg

Mass of the Moon m 2

=7.4×10 22 kg

Distance between the Earth and the Moon d=3.84×10 5 km=3.84×10 8 m

Gravitational Constant G=6.7×10 −11 Nm 2 /kg 2

Now, by using Newton’s law of gravitation

F= r 2Gm 1 m 2

F= (3.84×10 8 ) 2 6.7×10 −11 ×6×10 24 ×7.4×10 22

F= 14.8225×10 16297.48×10 35

F=20.069×10 19

F=20.1×10 19 N

Hence, the gravitational force of attraction is 20.1×10 19 N
