  • question_answer
    A ball of mass 160 g is thrown up at an angle of 60° to the horizontal at a speed of \[10m{{s}^{-1}}.\]The angular momentum of the ball at the highest point of the trajectory with respect to the point from which the ball is thrown is nearly \[(g=10m{{s}^{-2}})\]                                                                                        [JEE ONLINE 19-04-2014]

    A)   \[1.73kg{{m}^{2}}/s\]

    B)        \[3.0kg{{m}^{2}}/s\]

    C)   \[3.46kg{{m}^{2}}/s\]\

    D)        \[6.0kg{{m}^{2}}/s\]

    Correct Answer: C

    Solution :

    [c] Given : m = 0.160 kg
               
                v = 10 m/s
                Angular momentum
