    A body of mass \[0.1\,kg\]attains a velocity of \[10m{{s}^{-1}}\]in\[0.1\text{ }sec\]. The force acting on the body is:

    A)  \[10\,N\]             

    B)  \[10.01\,N\]

    C) \[5.\text{1}N\]            

    D)  \[100\text{ }N\]

    Correct Answer: A

    Solution :

    For Newton's second law of motion. \[F=ma=m\times \frac{\Delta V}{\Delta t}\] Here,   \[m=0.1\,kg,\,\,\frac{\Delta V}{\Delta t}=\frac{10}{0.1}m/{{\sec }^{2}}\] \[\Rightarrow \]\[F=0.1\times \frac{10}{0.1}=10N.\]
