Question
**Educational Note: Analyzing Gravitational Forces Between Earth and the Moon**

To understand the gravitational interactions between Earth and the Moon, consider the following scenario:

The Moon is held in its orbit around Earth by gravity. Earth has a mass approximately 78 times greater than the mass of the Moon. Which of the following is true?

1. The force of Earth acting on the Moon is greater than the force of the Moon acting on Earth.
2. The force of the Moon acting on Earth is equal to the force of Earth acting on the Moon.
3. The force of Earth acting on the Moon is less than the force of the Moon acting on Earth.
4. The force of the Moon acting on Earth is greater than the force of Earth acting on the Moon.

**Explanation**: 

According to Newton's Third Law of Motion, every action has an equal and opposite reaction. Therefore, the force exerted by Earth on the Moon is equal in magnitude and opposite in direction to the force exerted by the Moon on Earth. Hence, the correct answer is statement 2: The force of the Moon acting on Earth is equal to the force of Earth acting on the Moon.
