Quizplus · Accepted Answer

According to the Law of Gravitation, the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Therefore, if the distance between two stars decreases by half, the force between them will increase to four times as much (2^2=4).

When the Distance Between Two Stars Decreases by Half,the Force
