Alow-mass board of length 6 m rests on a cylinder (the "pivot"). a ball of mass 7 kg is placed on the end of the board. which of the diagrams below correctly shows the forces acting on the system of ball + board? (b) take the point at which the board touches the pivot as location . what is the magnitude of the torque on the system of (ball + board) about location ? n·m (c) which of the following statements are correct? the forces balance, so the angular momentum of the system about location will not change. because there is a torque, the angular momentum of the system will change in the next tenth of a second. the force by the pivot on the board contributes nothing to the torque about the pivot. the tolerance is +/-5%
