Identical particles are placed at the l1 =50-cm and l2 =80-cm marks on a meter stick of negligible mass. this rigid body is then mounted so as to rotate freely about a pivot at the 0-cm mark on the meter stick. if this body is released from rest in a horizontal position, what is the angular speed of the meter stick as it swings through its lowest position?
