    What is the angle between \[\overrightarrow{P}\] and  the resultant of \[(\overrightarrow{P}+\overrightarrow{Q})\] and \[(\overrightarrow{P}-\overrightarrow{Q})\]

    A)                 Zero      

    B)                 \[{{\tan }^{-1}}(P/Q)\]

    C)                 \[{{\tan }^{-1}}(Q/P)\]  

    D)                 \[{{\tan }^{-1}}(P-Q)/(P+Q)\]

    Correct Answer: A

    Solution :

                        Resultant \[\vec{R}=\vec{P}+\vec{Q}+\vec{P}-\vec{Q}=2\vec{P}\] The angle between \[\vec{P}\] and \[2\vec{P}\] is zero.
