प्रश्न
Which of the following example represent periodic motion?
A freely suspended bar magnet displaced from its N-S direction and released.
उत्तर
The motion of a freely-suspended magnet, if displaced from its N-S direction and released, is periodic. This is because the magnet oscillates about its position with a definite period of time.
