One end of meter stick is pinned to a table to that stick can rotate freely in aplane parallel to the table surface. Two horizontal forces are applied to the stick such that the rod does not rotate at all. One force has a magnitude of 2N and is applied perpendicular to the stick at the free end. The other force has a magnitude of 8N and acts at 30^(@) with respect in the length of the stick. At what distance from the pinned end is the 8N force applied.
