Mhmm okay thanks, so if the rope had a mass, the two people would exert a force to make sure the rope didn't fall.. But now what about this (still can't solve a tension problem); a 2.00-kg textbook rests on a frictionless, horizontal surface. A cord attached to the book passes over a pulley...

Thank you for all your replies, I see my F-2F theory didn't make sence. I still have trouble with tension though.. For example; if two people are pulling on a rope (with a force F) then how come the rope doesn't fall, since there are no upward forces to counter gravity? (excuse me for my...

Hi, I'm a bit confused with determining the tension in a rope. For example, when two people are puling on a rope, one with a force F and the other with a force 2F, how can you calculate the tension? I know the tension at any point in a rope is the magnitude of force acting at that point, and...
