Question

The body under the action and reaction of a force couple undergoes

• A. only translational motion
• B. only rotational motion
• C. both rotational and translational motion
• D. None of these

Answer 1

The correct option is B only rotational motion

A couple is a combination of two equal and opposite forces acting at a distance apart from each other. Thus, the net force is zero so there is no acceleration of centre of mass. The only effect produced is the rotation of the body due to resultant moment of the forces acting.
