Point masses m1 and m2 are placed at the opposite ends of a rigid rod of length L, and negligible mass. The rod is to be set rotating about an axis perpendicular to it. The position of point P on this rod through which the axis should pass so that the work required to set the rod rotating with angular velocity ฯ0 is minimum, is given by :2015 ๐_1/๐_2 L ๐_2/๐_1 L ๐_2/(๐_1+๐_2 ) L ๐_1/(๐_1+๐_2 ) L
