JEE Main & Advanced Physics NLM, Friction, Circular Motion Question Bank Conservation of Linear Momentum and Impulse

  • question_answer
    A force of 50 dynes is acted on a body of mass 5 g which is at rest for an interval of 3 seconds, then impulse is [AFMC 1998]            

    A)                         \[0.15\times {{10}^{-3}}\,Ns\]                    

    B)                         \[0.98\times {{10}^{-3}}\,Ns\]          

    C)           \[1.5\times {{10}^{-3}}\,Ns\]      

    D)             \[2.5\times {{10}^{-3}}\,Ns\]

    Correct Answer: C

    Solution :

                    Impulse, \[I=F\times \Delta t=50\times {{10}^{-5}}\times 3\]=\[1.5\times {{10}^{-3}}\ N\text{-}s\]
