- The displacement-time graphs of two moving particles make angles of 30° and 45° with the x-axis as shown in the figure. The ratio of their respective velocity is : Answer: 1. 1 : √(3) On a displacement-time graph, velocity equals the slope, v=tanθ . v₁/v₂=tan30^°/tan45^°=1/sqrt3/1=1:sqrt3 . The 30 degre... 1
