plzzz answer this it's urgent​

Answer 1

Answer:

The gravitational force between the Earth and the moon, F=2.01\times 10^{20}\ NF=2.01×10

20

N

Explanation:

Mass of the Earth, m_e=6\times 10^{24}\ kgm

e

=6×10

24

kg

Mass of the Moon, m_m=7.4\times 10^{22}\ kgm

m

=7.4×10

22

kg

The distance between the Earth and the moon, d=3.84\times 10^5\ km=3.84\times 10^8\ md=3.84×10

5

km=3.84×10

8

m

Let F is the force exerted by the earth on the moon. The formula of the force is given by :

F=G\dfrac{m_em_m}{d^2}F=G

F=6.7\times 10^{-11}\times \dfrac{6\times 10^{24}\times 7.4\times 10^{22}}{(3.84\times 10^8)^2}F=6.7×10
