Q41. Consider two particles moving along the x- axis. In terms of their coordinates x and x, dx their velocities are given as =X,-X and -X, respectively. When they start dt dt moving from their initial locations of x, (0) =1 and x, (0) =-1, the time dependence of both x and x, contains a term of the form e", where a is a constant. The value of a (an integer) 18..... *******
