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