Physics Answer Questions

What is the magnitude of the tension (in newton) in the middle of the spring?

  • Q : A light spring is compressed by pushing it at each end. The force applied at each end is 60 newton (this can be measured using a force gauge). What is the magnitude of the tension (in newton) in the middle of the spring?
  • A : Answer: 60 N
    Explanation: Let T be the magnitude of the tension in the middle of the spring.
    For each half of the spring,
    T - applied force = 0
    T - 60 N = 0
    T = 60 N
