    Which of the following examples represent periodic motion ?
    (a) A swimmer completing one (return) trip from one bank of a river to the other and back.
    (b) A freely suspended bar magnet displaced from its’N-S direction and released.
    (c) A hydrogen molecule rotating about its centre of mass.
    (d) An arrow released from a bow.
    (b) A freely suspended bar magnet displaced from its’N-S direction and released.
    (c) A hydrogen molecule rotating about its centre of mass.
    (d) An arrow released from a bow.
    (b) A freely suspended bar magnet displaced from its’N-S direction and released.
    (c) A hydrogen molecule rotating about its centre of mass.
    (d) An arrow released from a bow.
    (a) A swimmer completing one (return) trip from one bank of a river to the other and back.
    (b) A freely suspended bar magnet displaced from its’N-S direction and released.
    (c) A hydrogen molecule rotating about its centre of mass.
    (d) An arrow released from a bow.
    (b) A freely suspended bar magnet displaced from its’N-S direction and released.
    (c) A hydrogen molecule rotating about its centre of mass.
    (d) An arrow released from a bow.
    (b) A freely suspended bar magnet displaced from its’N-S direction and released.
    (c) A hydrogen molecule rotating about its centre of mass.
    (d) An arrow released from a bow.
    Ans : (a) It is not a periodic motion. Though the motion of a swimmer is to and fro but will not have a definite period.
    (b) Since a freely suspended magnet if once displaced from N-S direction and released, it oscillates about this position, it is a periodic motion
    (c) The rotating motion of a hydrogen molecule about its centre of mass is periodic.
    (d) Motion of an arrow released from a bow is non-periodic.
    (b) Since a freely suspended magnet if once displaced from N-S direction and released, it oscillates about this position, it is a periodic motion
    (c) The rotating motion of a hydrogen molecule about its centre of mass is periodic.
    (d) Motion of an arrow released from a bow is non-periodic.
    (b) Since a freely suspended magnet if once displaced from N-S direction and released, it oscillates about this position, it is a periodic motion
    (c) The rotating motion of a hydrogen molecule about its centre of mass is periodic.
