Question

The gravitational force with which the earth attracts the moon :

• A. Is less than the force with which the moon attracts the earth.
• B. Is equal to the force with which the moon attracts the earth.
• C. Is greater than the force with which the moon attracts the earth
• D. Varies with the phases of the moon.

Answer 1

The correct option is B Is equal to the force with which the moon attracts the earth.

The gravitational force between two bodies is given by $\frac{G{m}_1{m}_2}{r^2}$

Where $m_1,m_2$ are the masses of the bodies and $r$ is the separation between them.

So, the gravitational force between two bodies remains the same, and hence the gravitational force with which the earth attracts the moon is equal to the force with which the moon attracts the earth.
