Two forces equal in magnitude but opposite In direction and not acting along the same line constitute a couple. The movement of this couple will be:
Correct answer: B. Independent of the location of the origin
- A. Dependent on the location of the origin
- B. Independent of the location of the origin
- C. Zero
- D. Scalar product
Explanation
When two forces of equal magnitude opposite in direction and acting along parallel straight lines, then they are said to form a couple. The perpendicular distance between the two force forming a couple is called the arm of the couple.○The magnitude of the moment of couple or torque is equal to the product of one of the forces and the perpendicular distance between the lines of action of the two forces. The calculation is not linked with the axis of rotation. Hence it is independent of the position of the axis of rotation OR location of origin.Result: From the above discussion ,couple is independent of location of origin hence, B option is correct .

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
