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 ⍵₀ is minimum, is given by : [2015 RS]
(a) x = m₁/m₂ L
(b) x = m₂/m₁ L
(c) x = m₂L/m₁ + m₂ (d) x = m₁L/m₁ + m₂
