Question

30.
The displacement - time graphs of two moving particles make angle of 30° and 45° with the
x-axis the ratio of the two velocities is
S
15°) 308
Time
1) 13:1
2) 1:1
3) 1:2
4) 1:13​

Answer 1

Answer:

In both the cases, let the time be on the x-axis and displacement on the y-axis. We know that v=(dx/dt)=slope of the graph=tan theta.

Therefore (v1/v2)=tan 30°/tan45°=(1/√3)
