Problem
A uniform 2.0 m board of negligible mass is pivoted at its center. A 10 N weight is suspended 0.60 m to the right of the pivot. To counter this, a student can attach a rope to the left side of the board so that the rope pulls straight up. The rope can sustain a maximum tension of 40 N. What is the minimum distance from the pivot at which the rope must be attached for the board to be held in rotational equilibrium without exceeding the tension limit?
(a) 0.30m
(b) 0.15m
(c) 0.20m
(d) 0.12m
