Homework Statement


Two blocks, each with weight w, are held in place on a frictionless incline. Block A is connected to a wall with a rope and block B is connected with another rope to block A. Calculate the tension in both ropes in terms of w and θ. So, the rope connecting each other and also the one against the wall.


Homework Equations





The Attempt at a Solution



For the tension between the blocks I got Tbetween = w*sin θ.

But then for the tension of the rope connected to the wall. It would be have to be double because it's taking on the pull from block B and pull from block A. So the tension from the wall would be Twall = 2w*sin θ. Am I doing this correctly? Thanks.
