according to the law of gravitation, the force of attraction between two objects
depends on two types of variables, one of which is the masses of the objects.
which is the other variable?
∘ size of each object
∘ composition of each object
∘ distance between the objects
∘ magnetic field of each object

Explanation:

The law of gravitation (Newton's law of universal gravitation) is given by the formula \( F = G\frac{m_1m_2}{r^2} \), 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 their centers. So the force depends on the masses of the objects and the distance between them. The size, composition, and magnetic field of the objects are not factors in the law of gravitation.

Answer:

C. distance between the objects
