Gravitational attraction depends on the mass of the objects as well as their distance. The gravitational force between objects increases as the masses of the objects increase. The gravitational force decreases as the distance between objects increases. Using the model provided, what happens to gravitational force when the distance between two objects is decreased by half?
A) The gravitational attraction increases 4x.
B) The gravitational attraction increases 2x.
C) The gravitational attraction remains constant.
D) The gravitational attraction decreases by 1/4.

Please Help!!

When the distance between the two objects is decreased by half, then Option B: The gravitational attraction increases 2x.

Explanation:

'Gravitational force' is always the reverse to the space between the two objects.

If the distance between the two objects increases, gravitational force decreases between them. On the other hand, using the given model if the distance between the two objects is decreased by half then the gravitational force is doubled. Thus, option B is the correct option which says that gravitational force will become 2 times. It will not increase 4 times as per option A. It will also not remain constant as per option C, neither it will decrease by 1/4 as per Option D.

number 11 i would say 3rd or 4th

number 12 the 1st one
