Homework Help: Tension Problem

  1. Jun 2, 2009 #1
    1. The problem statement, all variables and given/known data
    A 10 kg block is at rest on a frictionless surface. The block is attached by a light inelastic string to a rigid wall. A force of 50 N is applied to the mass as shown in the diagram (attachment).

    2. Relevant equations
    The tension in the string is
    a 148N
    a 50N
    c 43.3N
    d 25N

    3. The attempt at a solution
    I think the tension on the string is 25N because sin30 is 0.5, and 0.5 x 50 = 25

    I can't see the diagram yet. Perhaps you could describe the diagram.

    That's incorrect. What are the horizontal and vertical components of that 50 N force?

    There's a 10kg blck at rest on a frictionless surface. On the left of it is a string attached to it which is attached to the rigid wall as well. On the right a force of 50N is applied to it at 30 degrees to the horizontal.

    ride4life: I agree with Doc Al. Your current answer is incorrect.
