1. The problem statement, all variables and given/known data A 1.0 kg pendulum bob is suspended from a string 1.0 m long. The pendulum swings until the string makes an angle of 22° with the vertical. At this point, if the pendulum is held with a string fastened to the bob and held horizontally, what would be the tension in the original string (not the horizontal one)? 2. Relevant equations Force of gravity parallel to the string = Force of tension = mgcos22 Force of gravity perpendicular to the string = mgsin22 3. The attempt at a solution I assumed that the horizontal rope would only affect the force of gravity perpendicular to the string, and that the tension in the original string would be the same as it was without a horizontal string holding it. Then my teacher made me question that assumption. Was I right, and she was just trying to make sure I was confident with my answer, or am I wrong? Thanks!
