Homework Help: Scale in elevator

  1. Oct 11, 2011 #1
    1. The problem statement, all variables and given/known data

    A person stands on an scale in an elevator.

    If the scale reads zero, should the student worry? Explain.

    2. Relevant equations



    3. The attempt at a solution

    I think the student would be in free fall and he should worry. The only force acting on the elevator would be gravity and the normal force and weight would be 0.

    Right?
