Action and reaction
Action and reaction have the same magnitude and opposite directions. According to Newton’s third law of motion, for every action, there is an equal and opposite reaction. This principle applies to interactions between two objects, where the forces exerted on each object are equal in magnitude and opposite in direction.

Action and reaction have the same magnitude and opposite directions; option [D]. According to Newton’s third law of motion, when one object exerts a force on another object (action), the second object exerts an equal but opposite force on the first object (reaction). These forces act on different objects, have equal magnitudes, and opposite directions. Therefore, all options are correct: [A] Work on two different objects, [B] Have the same magnitude, and [C] Have opposite directions. This fundamental principle of action and reaction is essential in understanding the dynamics of interactions between objects and is applicable in various fields of physics and engineering. It elucidates how forces are transmitted between objects and plays a critical role in analyzing and predicting the motion of systems governed by Newtonian mechanics.
