Physics Question on System of Particles & Rotational Motion
A couple produces
A
purely translational motion
B
purely rotational motion
C
both translational and rotational motion
D
no motion
Answer
purely rotational motion
Explanation
Solution
A couple defined more than two forces operating on a body in equal and opposing directions with an interval between their lines of action.
The pair is exerting no force as a consequence. As a result, the item does not travel linearly.
As a result, the coupling just causes the item to rotate.
