Homework Help: Tension, Force, and Newton's 3rd law

  1. Oct 30, 2007 #1
    1. The problem statement, all variables and given/known data

    A rope has forces exerted by pulling on each end. The rope is stationary. A point (P) divides the rope into a left side and right side.

    Assume the Right side exerts a force of magnitude T on the Left side. What is the magnitude of of the force exerted on the RIGHT side by the LEFT side?
    give answer in terms of T and other constants such a g.

    2. Relevant equations

    I am not sure but I know that Newtons 3rd law is to be applied.

    3. The attempt at a solution

    I know the force is directed towards the left, but I don't know of an equation that is right. I randomly guessed Tg and it told me I was off by a multiplicative factor.

    I can push you only as hard as you push me.

    I know, I still am not getting the equation correct :x ugh.

    AHH I got it. Simply T...they were tricking me with g.
