    Newtons second law of motion is

    A)  \[F=dp/dt\]         

    B)  \[F=mv\]

    C)  \[F=m{{v}^{2}}\]          

    D)  \[F={{m}^{2}}v\]

    Correct Answer: A

    Solution :

     From Newtons second law of motion, the rate of change of linear momentum of an object is directly proportional to the external force applied on it and change always takes place in the direction of applied force. \[F=\frac{dp}{dt}\]
