Question

which statement best describes newton’s third law? (a) for every action force, there is a reaction force of lesser magnitude and in the same direction. (b) for every action force, there is a reaction force of equal magnitude but opposite in direction. (c) for every action force, there is a reaction force of equal magnitude and in the same direction. (d) for every action force, there is a reaction force of lesser magnitude but in the opposite direction. a b c d

Explanation:

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means the reaction force has the same magnitude as the action force but acts in the opposite direction. Option (a) is incorrect as it says reaction force has lesser magnitude and same direction. Option (c) is incorrect as it says same direction. Option (d) is incorrect as it says lesser magnitude. Option (b) matches the definition of Newton's third law.

Answer:

b. For every action force, there is a reaction force of equal magnitude but opposite in direction.
