    Time-displacement \[(t-x)\]graph of two objects A and B is shown in figure. The ratio of their speeds \[({{V}_{A}}/{{V}_{B}})\] is \[(\tan {{37}^{o}}=3/4)\]

    A)  \[\frac{\sqrt{3}}{4}\]                                    

    B)  \[\frac{4}{\sqrt{3}}\]

    C)  \[\frac{4}{3\sqrt{3}}\]                  

    D)  \[\frac{3\sqrt{3}}{4}\]

    Correct Answer: A

    Solution :

    We have to find \[\frac{{{V}_{A}}}{{{V}_{B}}}=\frac{1/\tan {{53}^{o}}}{1/\tan {{30}^{o}}}=\frac{3/4}{\sqrt{3}}=\frac{\sqrt{3}}{4}\] Here note that slope of X-t graph gives the velocity at a particular in stat of time and area ofX-1 graph gives the displacement or distance covered by the particle
