  • question_answer
    In which of the following cases forces may not be required to keep the                                    [AIIMS 1983]

    A)                         Particle going in a circle            

    B)                         Particle going along a straight line          

    C)                         The momentum of the particle constant            

    D)                         Acceleration of the particle constant

    Correct Answer: C

    Solution :

                                If momentum remains constant then force will be zero because\[F=\frac{dP}{dt}\]
