In the given figure, thin uniform rod `A B` of mass `kg` moves translationally with acceleration `a=2 m / `s^(2)` due to two antiparallel forces `F_(1) ,F_(2)`. The distance between the points at which these forces are applied is equal to `0.2 m`. If force `F_(1)=8 N`, then find the length of the rod in meter.
