Verified Answer
Both earth and moon are subject to the gravitational force of the sun....
Concept:
Newton's law of gravitation: The force of attraction between any objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
- The force acts along the line joining the two bodies.
- The gravitational force is a central force that is It acts along the line joining the centers of two bodies.
- It is a conservative force. This means that the work done by the gravitational force in displacing a body from one point to another is only dependent on the initial and final positions of the body and is independent of the path followed.
- The moon revolves around the earth in a circular orbit (not perfectly circular). Sun exerts a gravitational force on both, the earth and moon. The major force acting on the moon is due to the gravitational force of attraction of the sun and earth and the moon is not always on the line joining the sun and earth.
- Two forces acting on the moon have different lines of action or the forces are not central, so it's motion will not be strictly elliptical.
Hence, option (2) is the correct answer.

B) The orbit of the moon will not be strictly elliptical because the total gravitational force on it is not central.
Explanation:
- The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
- The sun is much more massive than both the Earth and the moon, so it exerts a significant gravitational force on both of them.
- Both the Earth and the moon orbit around the sun due to the gravitational force exerted by the sun.
- According to Kepler's laws of planetary motion, the orbit of a planet or a satellite around the sun is an ellipse with the sun at one of the foci.
- However, the gravitational force between the Earth and the moon also plays a role in determining the moon's orbit.
- This force is not central, meaning it does not act along the line connecting the centers of the Earth and the moon.
- As a result, the orbit of the moon is influenced by this non-central force, causing deviations from a perfect ellipse.
- These deviations can be seen in the form of perturbations in the moon's orbit, such as changes in its eccentricity and variations in its orbital speed.
- Therefore, the orbit of the moon is not strictly elliptical because the total gravitational force on it is not central.
- Instead, it is influenced by the combined gravitational forces of the sun and the Earth, leading to a slightly perturbed orbit.
In conclusion, the correct answer is b) The orbit of the moon will not be strictly elliptical because the total gravitational force on it is not central.
