A0.10 kg meter stick is held perpendicular to a vertical wall by a 2.5 mm 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.
