    The engine of a car produces acceleration \[4\,m/{{s}^{2}}\] in the car. If this car pulls another car of same mass, what will be the acceleration produced                          [RPET 1996]

    A)             \[8\,m/{{s}^{2}}\]   

    B)             \[2\,m/{{s}^{2}}\]

    C)             \[4\,m/{{s}^{2}}\]   

    D)             \[\frac{1}{2}m/{{s}^{2}}\]

    Correct Answer: B

    Solution :

                    \[F=m\times a\], If force is constant then \[a\propto \frac{1}{m}\]. So If mass is doubled then acceleration becomes half.
