    A particle moves from (2, 3) m to (4, 1) m. The magnitude of displacement is

    A) \[2\text{ }m\]    

    B) \[2\sqrt{3}\,\,m\]

    C) \[2\sqrt{2}\,\,m\]           

    D) \[3\sqrt{2}\,\,m\]

    Correct Answer: C

    Solution :

    Displacement \[=\sqrt{{{\left( 4-2 \right)}^{2}}+{{\left( 3-1 \right)}^{2}}}=\sqrt{4+4}=2\sqrt{2}m\]
