The problem states: a 0.13-kg meter stick is held perpendicular to a wall by a 2.5-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. I assume the meter stick is not moving or it's in equilibrium, so wouldn't the tension simply be T = mg? Any help is greatly appreciated. Thanks in advance.
