Question

Which statement completes Newton’s Third Law of Motion about one object exerting a force on a second object? A. The forces are equal in magnitude and equal in direction.
B. The forces are equal in magnitude and opposite in direction.
C. The forces are opposite in magnitude and equal in direction.
D. The forces are opposite in magnitude and opposite in direction.

Answer 1

B. The forces are equal in magnitude and opposite in direction.

Answer 2

Answer : The correct option is, (B) The forces are equal in magnitude and opposite in direction.

Explanation :

Newton's first law of motion : It is defined as every body remains in a state of rest unless external force acted upon it.

Newton's second law of motion : It is defined as the acceleration of an object depends on its mass and applied force.

Formula used : F = ma

Newton's third law of motion : It states that for every action, there is an equal and opposite reaction. That means, forces are equal in magnitude but opposite in direction.

Hence, the correct option is, (B) The forces are equal in magnitude and opposite in direction.
