Which of the following motions will be produced by a pair of equal, opposite and non-collinear parallel forces acting on a body?
Oscillatory
Random
Rotational
Translational
Vibratory
Correct answer is C
A couple consists of two equal and opposite forces acting at a separation, so that net force becomes zero. When a couple acts on a body it rotates the body but does not produce any translational motion. Hence, only rotational motion is produced.
