The gravitational force of attraction between two objects is given by Newton's law of universal gravitation, which states that the force (\(F\)) is proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them:
\[ F = \frac{G \cdot m_1 \cdot m_2}{r^2} \]
Where:
- \(F\) is the gravitational force,
- \(G\) is the gravitational constant,
- \(m_1\) and \(m_2\) are the masses of the two objects (in this case, the star and the orbiting object),
- \(r\) is the distance between the centers of the two objects.
Since all the objects (X, Y, Z, and W) are at the same distance from the star, the distance \(r\) remains constant for all the objects. Therefore, the force of attraction primarily depends on the mass of the orbiting objects.
Thus, the gravitational force of attraction is strongest between the star and the object with the greatest mass.
Assuming you have information about the masses of objects X, Y, Z, and W, identify the object with the highest mass, and that will be the answer. Since the specific masses are not provided in your question, you'll need to look at the given values to determine which one is the largest.
If, for instance, object Z has the greatest mass, then the answer would be:
A. Z
If you have the specific masses, just replace the example with the object that has the highest mass.
