8. The mass of the sun is 1.99 x 1030 kilograms and its distance from Earth is 150 million kilometers (150 x 109 meters). What is the gravitational force between the sun and Earth?
please help

Answer:

[tex]F=3.53\times 10^{22}\ N[/tex]

Explanation:

Given that,

Mass of the Sun, [tex]m_1=1.99\times 10^{30}\ kg[/tex]

The distance of Sun from the Earth, [tex]r=150\times 10^9\ m[/tex]

We know that,

The mass of the Earth, [tex]m_2=6\times 10^{24}\ kg[/tex]

We need to find the gravitational force between the Sun and the Earth.

The formula between two masses is given by :

[tex]F=G\dfrac{m_1m_2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{1.99\times 10^{30}\times 6\times 10^{24}}{(150\times 10^9)^2}\\\\F=3.53\times 10^{22}\ N[/tex]

So, the gravitational force between the Sun and the Earth is [tex]3.53\times 10^{22}\ N[/tex]
