    Two vectors \[\overrightarrow{A}\]and \[\overrightarrow{B}\]lie in a plane, another vector \[\overrightarrow{C}\]lies outside this plane, then the resultant of these three vectors i.e.,\[\overrightarrow{A}+\overrightarrow{B}+\overrightarrow{C}\]                                       [CPMT 1983]

    A)                 Can be zero

    B)                             Cannot be zero

    C)                 Lies in the plane containing \[\overrightarrow{A}+\overrightarrow{B}\]

    D)                 Lies in the plane containing \[\vec{C}\]

    Correct Answer: B

    Solution :

                        If \[\vec{C}\] lies outside the plane then resultant force cannot be zero.
