Q9 pls answer it urgently

9 If the displacement-time graph for the two particles A
and B are straight lines inclined of 30 ° and 60 ° with the
time axis, then the ratio of velocities VA :
VB will be

A   3   :   1          
                 
                 
                 
                 
  B   1   :   3 C   3   :   1
                 
                 
                 
                 
    D   1   :   3

Dear student,
The velocity in the displacement time graph is calculated as slope
of line which is formed between displacement and time graph=Tan

θ
Va:Vb=Tan 
θ (A)/Tan 
θ(B)
Va/Vb=Tan (60)/â€‹Tan (30)
Va/Vb=31/3=3/1
So, the correct answer is a which is 3:1
