The answer is VA : VB = 1 : √3
Here, the graphs make an angle of 450 & 600 with time axis i.e. with x-axis.
So, in case of displacement-time graph, the velocity is equal to slope of graph.
In case of A, velocity = VA = tan (450) = i units
In case of B, velocity = VB = tan (600) = √3 units.
So, ratio of velocities is VA : VB = 1 : √3
