Two stones are thrown up simultaneously from the edge of a cliff 240 m high with initial speed 10 m/s and 40 m/s respectively. Which of the following graph best represents the time variation of relative position of the second stone with respect to the first ? (Assume stones do not rebound after hitting the ground and neglect air resistance, take g=10 m/s 2 )
