You place a 3.0-m-long board symmetrically across a 0.5-m-wide chair to seat three physics students at a party at your house. if 65-kg dan sits on the left end of the board and 50-kg tahreen on the right end of the board, where should 54-kg komila sit to keep the board stable? ignore the mass of the board and treat each student as point-like objects. the positive x-direction is to the right, and the origin is at the center of the chair.
