Two particles 1 and 2 move along +$$x$$-axis such that 2 is ahead of 1 by 4m both on the right side of the origin.The velocity of 1 is directly proportional to the position of 2, and the velocity of 2 is directly proportional to the position of 1, the proportionality constant being the same, equal to $$(\ln2) \text{ sec}^{-1}$$. Find the time in seconds after which their separation becomes $$1\text{ m}$$.
