Which of the following type of motion does a body undergo when acted upon by a couple?V
Answer Details
When a body is acted upon by a couple, it undergoes rotational motion.
A couple is a pair of equal and opposite forces that are not in the same line of action. When these forces are applied to a body, they create a turning effect or torque that causes the body to rotate around a fixed axis. This rotation is known as rotational motion.
In contrast, vibrational motion refers to the back-and-forth or oscillatory motion of a body around its equilibrium position, while translational motion refers to the straight-line motion of a body from one point to another. Random motion is the unpredictable and chaotic motion of particles in a gas or liquid.
Therefore, the correct answer is: "rotational."
