    A car runs at a constant speed on a circular track of radius 100 m, taking 62.8 seconds in every circular loop. The average velocity and average speed for each circular loop respectively, is

    A) 0, 10 m/s          

    B)        10 m/s, 10 m/s

    C) 10 m/s, 0                      

    D) 0, 0

    Correct Answer: A

    Solution :

    [a]  Distance covered in one circular loop\[=2\pi r\] \[=2\times 3.14\times 100=628\,m\] Speed\[=\frac{628}{62.8}=10\,m/\sec \] Displacement in one circular loop =0 Velocity\[=\frac{0}{\text{time}}=0\]
