Question

saturn orbits around the sun, but saturn acts on the sun as well. what is the correct relationship of forces acting between the sun and saturn?

Explanation:

According to Newton's third law of motion, when one object exerts a force on a second object, the second object exerts an equal - in - magnitude and opposite - in - direction force on the first object. In the case of the sun and Saturn, the gravitational force that Saturn exerts on the sun and the gravitational force that the sun exerts on Saturn are action - reaction forces. So these two forces should be equal in magnitude and opposite in direction, and they act on different objects (the sun and Saturn respectively). Looking at the options, the second diagram (with a left - pointing arrow and a right - pointing arrow) represents two forces that are equal in magnitude, opposite in direction, and acting on different objects, which is consistent with the action - reaction force relationship between the sun and Saturn.

Answer:

The second diagram (with a left - pointing arrow and a right - pointing arrow) represents the correct force relationship between the sun and Saturn. (If we assume the options are labeled as A, B, C with A being the first diagram, B the second, C the third, then the answer is B. Option Text)
