A (В (D Students are doing an experiment near an empty pool. A student of mass 40 kg is standing on one end of a board as the board hangs over the pool as shown. The board is of uniform density, has a length I, and is positioned such that the pivot point is L/3 from the end of the board. The board is just about to tip over into the pool. How far from the pivot point must a 60 kg student stand so that the board is just about to tip over? E 2L/9 2L/3 L/3 L/2 -L/3- 3L/2 Board L Pool <
