Point masses` m_1` and `m_2` are placed at the opposite ends of a rigid rod of length L, and negligible mass . The position of point p on this rod through which the axis should p on this rod through which the axis should pass so that the work required to set the rod rotating with angular velocity `omega_0` is minimum , is given by:
.

`x=m_2L/(m_1+m_2)`

`x=m_1L/(m_1+m_2)`

`x=(m_1)/(m_2)L

`x=(m_2)/(m_1)L`
