Q.54 Consider two particles moving along the x-axis. In terms of their coordinates xi and x2, their velocities are given as =x2-X and = x-X2, respectively. When they start moving from their initial locations of x, (0)= 1 and x2 (0)=-1, the time dependence of both xi and x2 contains a term of the form eat, wherea is a constant. The value of a (an integer) is: dt dt
