    A particle has angular momentum equal to A. The angular momentum becomes 4A after 4 sec. Find the torque applied:

    A) \[\frac{A}{4}\]                                  

    B) \[\frac{3A}{4}\]                

    C)         4A                         

    D)         3A

    Correct Answer: B

    Solution :

    Using the formula for torque \[\tau =\frac{\text{difference in angular momentum}}{\text{time}}\] \[\tau =\frac{4A-A}{4}=\frac{3A}{4}\]
