MCQ
A couple is acting on a two particle systems. The resultant motion will be:
- ✓Purely rotational motion.
- BPurely linear motion.
- CBoth $A$ and $B.$
- DNone of these.
✓
Answer
Correct option: A.
Purely rotational motion.
A couple consists of two equal and opposite forces whose lines of action are parallel and laterally separated by the some distance.
Therefore, net force $($or resultant$)$ of a couple is null vector, hence there is no translational acceleration, only rotational motion will be there.
