Answer:

The gravitational force of an object that has half the mass is C) 9G.

Explanation:

Newton's Law of Gravitation:

We can see that the gravitational force, , and mass (let's combine M * m into just "m"), , are directly proportional to each other.

This means that if increases, also increases.

Therefore, if the mass is halved, that means that the gravitational force is also going to be halved.

The answer is 18G / 2 = 9G, which corresponds to answer C) 9G.
