12 meter long uniform plank weighing 2000N balanced on fulcrum. if the 800N object is placed on the beam 1.5 meters from it's right end where, if it all, can the fulcrum be moved such that this new system remains level and in equilibrium?
A) the system cannot be in equilibrium unless another weight is added to the left side
B) the system cannot be in equilibrium because the beam ins't long enough
C) moving the fulcrum 1.3 meters to the right of the center will balance it
D) moving the fulcrum 0.6 meters to the right of the center of the beam will balance it
