Two particles P and Q are in motion. Their displacement time graphs are respectively inclined at 30∘ and 60∘ to time axis. Their ratio of velocities VPVQ is
Velocity = Slope of the line formed in displacement v/s time graph = Tanθ
Vp : Vq = Tan30 : Tan60 = (1/√3) : √3= 1 : 3
Ratio of velocities of P:Qis 1 : 3
