the answer is somewhat clear.

Explanation:

According to Newton's law of universal gravitation, the gravitational force between two objects is directly proportional to the product of their masses. If the moon's size doubles (assuming its mass also doubles as mass is related to size for a given density), and the distance remains the same, the gravitational force between Earth and the moon will also double.

Answer:

The gravitational force between Earth and the moon would double because the gravitational force is directly proportional to the mass of the moon, and when the moon's mass doubles while the distance stays constant, the gravitational pull between them increases by a factor of two.
