  • question_answer
    Direction ratios of two lines are a, b, c and \[\frac{1}{bc},\frac{1}{ca},\frac{1}{ab}\]. The lines are

    A)                                                               Mutually perpendicular

    B)                                                               Parallel

    C)                                                               Coincident

    D)                                                               None of these

    Correct Answer: B

    Solution :

                                                                  As \[\frac{a}{(1/bc)}=\frac{b}{(1/ca)}=\frac{c}{(1/ab)},\] Hence lines are parallel.
