To calculate the gravitational force between two objects, you need:
- The mass of the two objects
- The distance between the two objects
The gravitational force can be calculated using Newton's law of universal gravitation, which is given by the formula:
\[ F = \frac{G \cdot m_1 \cdot m_2}{r^2} \]
where:
- \( F \) is the gravitational force,
- \( G \) is the gravitational constant,
- \( m_1 \) and \( m_2 \) are the masses of the two objects, and
- \( r \) is the distance between the centers of the two objects.
So, the correct response would be the mass of the two objects and the distance between the two objects.
