    A body of mass 10 kg is moving with a constant velocity of 10 m/s. When a constant force acts for 4 s on it, it moves with a velocity 2 m/s in the opposite directions. The acceleration produced in it is

    A)  \[4:1\]                 

    B)  \[1:3\]

    C)  \[3:1\]                 

    D)  \[1:9\]

    Correct Answer: B

    Solution :

                    From equation of motion \[\frac{r_{A}^{2}}{R_{B}^{2}}\] \[\frac{R_{B}^{2}}{R_{A}^{2}}\]                 \[3m/{{s}^{2}}\] \[-3m/{{s}^{2}}\]              \[0.3m/{{s}^{2}}\]
