A couple produces (a) linear and rotational motion (b) no motion (c) purely linear motion (d) purely rotational motion

Answer: (d). A couple is two equal, opposite, non-collinear forces: net force = 0, net torque ≠ 0. No net force means no translation; the torque gives rotation only. So the answer is (d) purely rotational motion.

A couple produces

Show answer and solution

Answer: (d)

A couple is two equal, opposite, non-collinear forces: net force = 0, net torque $\neq 0$ .
No net force means no translation; the torque gives rotation only.
So the answer is (d) purely rotational motion.
