The correct answer is B. Decreases
Step-by-step explanation:
Gravitational force is a natural force that occurs as objects composed of mass attract others. This applies to planets, stars, and other massive objects but also objects with less mass. Additionally, the gravitational force is described through the formula F (Gravitational Force) = G (Gravitational constant) M m (mass of the two objects) / r2 (distance).
This shows the distance is key for gravitational force; indeed, as distance increases gravitational force decreases and vice versa. This explains why the gravitational force has a great effect on all elements in the Earth, but other planets do not have this effect as the gravitational force exerted by these objects is weak due to the great distance. Thus, as the distance between two objects increases, the gravitational force decreases.
