Question:
Two stones are thrown up simultaneously from the edge of a cliff $240 \mathrm{~m}$ high with initial speed of $10 \mathrm{~m} / \mathrm{s}$ and $40 \mathrm{~m} / \mathrm{s}$ 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 $\mathrm{g}=10 \mathrm{~m} / \mathrm{s}^{2}$ ) (The figure are schematic and not drawn to scale)
Correct Option: 1
Solution:
