Question

Which type of motion is represented by the plastic ruler shown below?

  1. Circular
  2. Translatory
  3. Rotatory
  4. Vibratory

Hint:

When a body moves to and fro about its mean position is called vibratory motion.

The correct answer is: Vibratory


     The plastic ruler as shown in the figure moves up and down at regular intervals of time. Hence, it is said to be in vibratory motion.
