What is NOT true of 2 forces that give rise to a couple?
Correct answer: B. They both act at the same point
- A. They act in opposite directions
- B. They both act at the same point
- C. They both act on the same body
- D. They both have the same magnitude
Explanation
Two equal and opposite parallel forces not acting along the same line form a couple.

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
