Newton's Law of Universal Gravitation states that all objects with mass exert a gravitational force on each other, and this force is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Therefore, the correct answer from your options is:
B: all objects with mass have gravity.
To clarify, the law can be summarized with the formula:
\[ F = G \frac{m_1 m_2}{r^2} \]
where:
- \( F \) is the gravitational force between two objects,
- \( G \) is the gravitational constant,
- \( m_1 \) and \( m_2 \) are the masses of the objects, and
- \( r \) is the distance between the centers of the two objects.
The statement about gravity depending on the mass relates to this principle, but the specific phrasing A or C does not accurately capture the law.
