A non uniform rod OM (of length l m) is kept along x-axis and rotating about an axis AB, which is perpendicular to rod as shown in the figure. The rod has linear mass densty that varies with the distance x from left end of the rod according to `lamda=lamda_(0)((x^(3))/(L^(3)))`
Where unit of `lamda_(0)` is kg/m. What is the value of x so that moment of inertia of rod about axis AB `(I_(AB))` is minimum?
