Effect of a couple is

Options

  1. Apurely linear motion
  2. Bpurely rotational motion
  3. Clinear and rotational motion
  4. Dno motion

Correct answer

B. purely rotational motion

Step-by-step solution

A couple mainly comprises of two paralleI forces which are both equal in magnitude but opposite in direction. There is no line of action along which both forces act and hence it produces only rotational motion.
