A 75.0-kg and 5.00-m plank is supported by two fulcrums (take the left end to be the origin x=0). When the fulcrums are at x-0 and x=2.50 m, the plank is in equilibrium. However, when the fulcrums are at x-2.00 m and x=2.50 m, the plank starts to rotate, with its left end falling to the ground. To keep the equilibrium while in this configuration, a mass 21.75 kg is placed at x=5.00 kg. Where is the center of gravity of the plank located with respect to the left end? O 1.35 m O 1.13 m O 1.50 m O 2.00 m
