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.

The gravitational force between the Earth and the Moon is a fundamental aspect of their interaction. According to Newton's law of universal gravitation, every mass attracts every other mass with a force that is equal in magnitude and opposite in direction.

Key Points to Consider

• Equal Forces: The force with which the Earth attracts the Moon is equal to the force with which the Moon attracts the Earth.
• Mass and Distance: The strength of this gravitational force depends on the masses of both bodies and the distance between them.
• Constant Relationship: This force does not vary with the phases of the Moon; it remains consistent as long as the distance and masses are unchanged.

Correct Answer

The correct choice is (B) - the gravitational force with which the Earth attracts the Moon is equal to the force with which the Moon attracts the Earth.
