# Fixed Pulley with Two Ropes

## Homework Statement

There is a fixed pulley lifting weight of 2N. Attached to the weight there are two ropes. On the other side of the pulley there are two man standing, one of them just below the pulley and the other is further away (Illustrated). The weight is on balance, it is not moving. The man just below the pulley is using N force. What force the other man is using?

## The Attempt at a Solution

I argue that the other man is also using force N. But my friend is saying that he is not.

Any idea?

Hard to really help without giving you the answer (especially since there are only two choices!)
Hint - without friction, the tension in the rope is the same everywhere.

That's what I am thinking (If I guessed your answer correctly). If there was only one rope, then one man would have to use 2N force. But since there are two ropes, each has to pull with N. But my friend is arguing that we need to find the composite force for two, because the angles are different. Isn't it on the pulley the force 2N. One is using N and the other should use N as well?
This is not an assignment question by the way. Just for fun. We haven't seen any two rope pulleys before.
