explain why the string stretches while the system is rotating?

  • physics -

    What system?
    How do you expect us to know what you are talking about?

  • physics -

    As the system rotates, the mass is moved in a circle which means that there is a net force acting on it and is directed towards the center. That force is provided by the spring which has to be streched in order to provide the force needed.
