    Maximum and minimum magnitudes of the resultant of two vectors of magnitudes P and Q are in the ratio \[3:1.\]Which of the following relations is true

    A)                 \[P=2Q\]

    B)                             \[P=Q\]

    C)                 \[PQ=1\]             

    D)                 None of these

    Correct Answer: A

    Solution :

                        According to problem \[P+Q=3\ \text{and }P-Q=1\] By solving we get\[P=2\ \text{and }Q=1\]\        \[\frac{P}{Q}=2\]Þ \[P=2Q\]
