Two objects aren't in contact,but they affect each other via the gravitational force,and there aren't any other forces acting on either object.Which statement is always true?

Question

Quizplus · Accepted Answer

According to Newton's Law of Universal Gravitation, the gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. Since the masses of the two objects are equal, the force they exert on each other is also equal in magnitude. Therefore, option A is always true. The direction of the gravitational force, however, is dependent on the distance between the objects and their relative positions, so option B is not necessarily true. The magnitude and direction of the acceleration of each object depend on their individual masses and the distance between them, so options C and D are also not always true.
