Two stones are thrown up simultaneously with initial speeds of `u_(1)` and `u_(2)(u_(2)gtu_(1))`. They hit the ground after 6 s and 10 s respectively. Which graph in fig. correctly represents the time variation of `Deltax=(x_(2)-x_(1))` the relative position of the second stone with respect to the first upto `t=10` s? Assume that the stones do not rebound after hitting the ground.
