Tension in the rope of tug of war

  1. Feb 8, 2013 #1
    1. The problem statement, all variables and given/known data
    In a tug of war, five men on each team pull with an average force of 500 N each. What is teh tension in the center of the rope.
    A. zero B. 100N C. 500N D. 2500N E.5000N

    2. Relevant equations

    3. The attempt at a solution
    I know this isn't a very complicated question but I am not sure how the two forces on each side would effect it. T first i though they would cancel out, but there has to be some tension, so are they compounded? I am really unsure. Any explanation would be greatly appreciated.

    Also sorry if this is in the wrong section

    Suppose you broke the rope in the middle, and replaced one of the teams, together with their half rope, with a spring scale (like the ones they use to weigh vegetables in a supermarket) nailed to a rigid post. Would it matter whether the spring and post were supplying the force to hold the other team in place? What would be the reading on the spring scale?
