Answer:
correct answer will be option D.
Step-by-step explanation:
the gravitational force between two point forces =
where G is the gravitational constant , M and m are masses of two bodies and r is the distance of separation between two bodies.
here we can see that force is not constant as the distance of separation r will keep changing with time as they come closer.
and also the force depend not only on masses but also on r.
therefore when r is lesser force is greater so option D is correct answer.
