Consider two blocks of masses m and 2m which are connected by an ideal spring of spring constant k. Complete arrangement is placed on smooth horizontal plane. At t = 0 velocities 3 m/s and 6 m/s are given to m and 2m as shown in figure. If t = t₁, and t = t₂ is the first time instants (t₁ & t₂ ≠ 0) when block of mass m have maximum velocity and 2m have minimum velocity respectively then value of |t1-2t2| will be equal to
