Question

Which of these forces exist between earth and moon?

gravitational force
electromagnetic force
weak nuclear force
strong nuclear force

Answer 1

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

Answer 2

The that exist between earth and moon is
`1.97* 10^(20)\ N`

Step-by-step explanation:

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

`F=G(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* 10^(-11)* (5.97* 10^(24)\ kg* 7.34* 10^(22)\ kg)/((384400* 10^3\ m)^2)`

`F=1.97* 10^(20)\ N`

Hence, the force that exists between earth and moon is gravitational force and it is equal to
`1.97* 10^(20)\ Newton`
