    If for two vectors \[\overrightarrow{A}\] and \[\overrightarrow{B},\overrightarrow{A}\times \overrightarrow{B}=0,\]the vectors

    A)                 Are perpendicular to each other

    B)                 Are parallel to each other

    C)                 Act at an angle of 60°     

    D)                 Act at an angle of 30°

    Correct Answer: B

    Solution :

                        \[\vec{A}\times \vec{B}=0\]\ \[\sin \theta =0\]\ \[\theta =0{}^\circ \]                 Two vectors will be parallel to each other.
