    A force of 100 dynes acts on mass of 5 gm for 10 sec. The velocity produced is                                 [MNR 1987]

    A)                         2 cm/sec            

    B)                           20 cm/sec            

    C)                         200 cm/sec                 

    D)                         2000 cm/sec

    Correct Answer: C

    Solution :

                                Acceleration \[a=\frac{F}{m}=\frac{100}{5}=20\ cm/{{s}^{2}}\]             Now \[v=at=20\times 10=200\,cm/s\]
