Question

Which of these forces exist between earth and moon?

Answer 1

Answer:

The that exist between earth and moon is $1.97\times 10^{20}\ N$

Explanation:

Gravitational force acts between earth and moon. It is given by :

$F=G\dfrac{m_1m_2}{r^2}$

Where

m₁ = mass of earth

m₂ = mass of moon

G = constant

r = distance between earth and moon

By putting the value of above parameters we ca calculated the value of gravitational force i.e.

$F=6.67\times 10^{-11}\times \dfrac{5.97\times 10^{24}\ kg\times 7.34\times 10^{22}\ kg}{(384400\times 10^3\ m)^2}$

$F=1.97\times 10^{20}\ N$

Hence, the force that exists between earth and moon is gravitational force and it is equal to $1.97\times 10^{20}\ Newton$

Answer 2

Between Earth and Moon there is a gravitational force that exists.
