A 0.13 kg meter stick is held perpendicular to a wall by a 2.7 m string going from the wall to the far end of the stick.

(a) Find the tension in the string.

(b) If a shorter string is used, will its tension be greater than, less than, or the same as that found in part (a)?

(c) Find the tension in a 2.0 m string.

2. Relevant equations

Torque=Nr?

3. The attempt at a solution

I discovered the angle to be 68.38 degrees, and I thought that, since the y-component of the force cancels out mg, T=mg/sin(theta). Why is it wrong?
